How to find the greatest common factor of mathematics in volume two of grade five?
Be clear and concise. Don't talk nonsense. Give an example to illustrate how to use this method
First of all, write out the factors of two or three numbers in the title (if you want all, if you don't have all, you can't find them), then find out the same number in the title and find the biggest one
give an example:
What is the greatest common factor of 24 and 36?
Answer: factor of 24: 1, 24, 2, 12, 3, 8, 4, 6
Factors: 1,3,6,6,6,36
Common factors: 1, 2, 3, 4, 6, 12
Maximum common factor: 12
A: the greatest common factor of 24 and 36 is 12
Another method is short division. I'll give you a direct example
give an example:
What is the greatest common factor of 24 and 36?
Answer: 24 = 2 * 2 * 2 * 3
36=2*2*3*3
Common factor: 2,2,3
2*2*3=12
A: the greatest common factor of 24 and 36 is 12

The greatest common factor of the two numbers is 4, and the least common multiple is 84. These two numbers may be () and (), or () and（
The greatest common factor of two numbers is 4 and the least common multiple is 84. These two numbers may be (4) and (84), or (12) and (28)
Reason: because two numbers in the multiple relationship, their greatest common divisor is a smaller number, and the least common multiple is a larger number
84 and 4 are multiple relations, so the first answer is easy to get; the second answer should be from the divisor of 84 and the multiple of 4, it is not difficult to find 12 and 28
Hello, happwr2001
Wrong answer on the first floor. The greatest common factor of 12 and 84 is 12, not 4.
The greatest common factor of two numbers is 4, and the least common multiple is 84,
These two numbers may be (4) and (84)
It could also be (12) and (28)
Because 84 = 4x3x7.
4 as the greatest common divisor. Therefore, the combination that meets the conditions can be:
12 and 28
4 and 84
What is the definition of plural?
Complex number refers to the number a + bi which can be written in the following form, where a and B are real parts and I is imaginary number unit (i.e. - 1 open root). It was first introduced by Cardan, a scholar in Milan, Italy, in the 16th century. After the work of d'Alembert, demover, Euler, Gauss and others, this concept gradually became popular among mathematicians
(comparison of the least common multiple and the greatest common factor)
Use 42 roses and 36 carnations to tie into a bouquet, so that the number of roses in each bouquet is the same, and the number of carnations is the same, and all the flowers are just divided and there is no surplus. How many flowers can be tied at most? How many at least are there in each bouquet?
At most 6 bunches and at least 13 flowers per bunch
You can tie up to six bunches of flowers. There are 7 roses and 6 carnations in each bunch.
You can tie up to six bunches of flowers. There are 7 roses and 6 carnations in each bunch.
Up to 6 bunches of flowers can be tied, each with 7 roses and 6 carnations. Listen to the teacher in class, I won't tell you next time!
6 13
42 / 36 = 7 / 6, 7 roses and 6 carnations tied into a bouquet, a total of 6
It can be divided into 6 bundles at most, with at least 13 flowers in each bundle, including 7 roses and 6 carnations.
Because GCD (42,36) = 6, where GCD is the greatest common divisor
The origin of plural
In order to find the roots of quadratic and cubic equations with one variable, we will encounter the problem of finding the square roots of negative numbers. In 1545, Italian mathematician girolamocardano (1501-1576) first studied imaginary numbers and made some calculations in his book Da Shu, After that, the German mathematician Gottfried wilbcl mlcibniz (1646-1716), the Swiss mathematician Leonhard Euler (1707-1783) and the French mathematician abrabamde Moivre (1646-1716) formally used the two terms "real number" and "imaginary number", From 1667 to 1754, etc. studied the relationship between imaginary number and logarithmic function, trigonometric function, etc. in addition to solving equations, they also applied it to calculus and other aspects, and obtained many valuable results, which made some more complex mathematical problems simple and easy to deal with. About 1777, Euler first used I to express the square root of - 1. In 1832, German mathematician Carl Fridrich Gauss, From 1777 to 1855, Gauss introduced the concept of complex number for the first time. A complex number can be represented by a + bi, where a and B are real numbers and I represent imaginary units. In this way, the imaginary number and real number are unified. Gauss also corresponded the complex number with the points in the complex plane one by one, and gave a geometric explanation of the complex number. Soon, people connected the complex number with the plane vector, It has been widely used in electrical engineering, fluid mechanics, vibration theory and wing theory. Then, the theory of "complex variable function" with complex number as variable has been established, which is a new and powerful branch of mathematics. Therefore, we should deeply realize the truth that "virtual number is not virtual"
In his book important art published in 1545, Jerome Cardan (1501-1576), an Italian scholar in Milan in the 16th century, published the general solution of cubic equation, which was called "Cardan formula" by later generations. He was the first mathematician to write the square root of negative number into the formula, and was discussing whether it was possible to divide 10 into two parts, so that their product was equal to 40, He wrote the answer as = 40. Although he thought and the two expressions were meaningless, imaginary and illusory, he still divided 10 into two parts and made their product equal to 40. Descartes (1596-1650), a French mathematician, gave the name of "imaginary number". In his geometry (1637), he made "imaginary number" correspond to "real number", The imaginary number spread
In 1702, the German mathematician Leibniz (1646-1716) said: "the imaginary number is a subtle and strange hiding place for gods to escape, It's probably an amphibian in the two realms of existence and nihilism, "said Euler (1707-1783), a Swiss mathematician." all mathematical martial arts that are shaped and practiced are impossible, imaginary numbers, because they represent the square root of negative numbers. For such numbers, we can only conclude that they are neither nothing nor more than nothing, In 1747, French mathematician d'Alembert (1717-1783) pointed out that if the imaginary number is operated according to the four operation rules of polynomials, the real rational thing can stand the test of time and space, and finally occupy its own place, Then its result is always in the form of (a, B are real numbers) (Note: the mark = - I is not used in current textbooks, but = 1 is used). The French mathematician demover (1667-1754) discovered the formula in 1730, which is the famous demover theorem. Euler developed the famous relation in 1748, In his paper differential formula (1777), he first used I to express the square root of 1, and created the symbol I as the unit of imaginary number. In fact, "imaginary number" is not imaginary, but it does exist. In 1779, the Norwegian surveyor chensell (1745-1818) tried to give an intuitive geometric explanation to this kind of imaginary number, and first published his practice, However, the academic community did not pay attention to it
German mathematician Gauss (1777-1855) published the image representation of imaginary numbers in 1806. That is to say, all real numbers can be represented by a number axis. Similarly, imaginary numbers can also be represented by a point on a plane. In rectangular coordinate system, take point a corresponding to real number a on the horizontal axis and point B corresponding to real number B on the vertical axis, and draw a line parallel to the coordinate axis through these two points, In 1831, Gauss used the group of real numbers (a, b) to represent the complex number a + bi, and established some operations of the complex number, so that some operations of the complex number are also "algebraic" like real numbers. In 1832, he first proposed the term "complex number", In this paper, two different methods of representing the same point on the plane, rectangular coordinate method and polar coordinate method, are synthesized. They are unified in the algebraic and triangular forms of representing the same complex number. The point on the number axis corresponds to the real number one, and is extended to the point on the plane corresponds to the complex number one. Gauss regards the complex number not only as a point on the plane, but also as a vector, By using the corresponding relation between complex number and vector, this paper expounds the geometric addition and multiplication of complex number. So far, the complex number theory has been established completely and systematically
Through the unremitting efforts of many mathematicians for a long time, the complex number theory has been deeply explored and developed, which makes the ghost of the mathematical field for 200 years, the imaginary number, take off the mysterious veil and show its true colors. It turns out that the imaginary number is not empty. The imaginary number has become a member of the family of numbers, so that the real number set has been expanded to the complex number set
Divide 46 pieces of fruit candy and 38 pieces of chocolate equally to the students in a group. As a result, there is one piece of fruit candy left and three pieces of chocolate left______ A classmate
46-1 = 45 (block), 38-3 = 35 (block), 45 = 3 × 3 × 5, 35 = 5 × 7, so the greatest common factor of 45 and 35 is 5, that is, there are at most 5 students in this group
Definition of English plural
In general, s is added directly to a word- pens.map ——Maps. Ending with a consonant letter and y, you should change y to I, and then add es. For example, family - familiase. Ending with s, x, CH, SH and so on, you should add es. For nouns ending with a vowel letter and y, you should directly add S. for example, boy = BOS, ending with f or Fe, changing f or Fe into V, and adding es. For example, knife = knives
In English, nouns can be divided into countable nouns and uncountable nouns. There is no singular or plural form for uncountable nouns. When the number of countable nouns is greater than one, the plural form is needed, such as an apple; two apples
Generally, adding s after a word is plural, but the plural of some words is more special, such as foot plural is feet, mouse plural is mice and so on
Mathematical problems (about the greatest common factor and the least common multiple)
The greatest common factor of a and B is 12 and the least common multiple is 252
36=12*3
252=36*7
Because the greatest common factor of a and B is 12, the factor of B must not contain 3, otherwise the greatest common factor is 12 * 3 = 36, but it must contain 7
Because the least common multiple of a and B is 252, the factor of 36 does not contain 7, so the factor of B must contain 7, and there is no other factor except 12 and 7 (otherwise the least common multiple is not 252)
So B is 12 * 7 = 84
12*252/36=84
