What is the greatest common factor and the least common multiple
The greatest common factor is to find the greatest divisor among several divisors with the same number
The least common multiple is the smallest of the same number of multiples
What's the problem?

There are two natural numbers whose least common multiple is 20 times of the greatest common divisor, and their difference is 7?
Please give detailed explanation or analysis ideas,
The least common multiple is 20 times of the greatest common divisor, indicating that the product of the unique factors of the two numbers is 20
Another 20 = 1 * 20 = 2 * 10 = 4 * 5
Let the greatest common divisor be x and X be an integer, then the two numbers are x and 20x, or 2x and 10x, or 4x and 5x
The difference between the two is 7
Then 20x-x = 7, x = 7 / 19 are not consistent with the meaning of the title
10x-2x = 7, x = 7 / 8
5x-4x = 7, x = 7 is consistent with the question
So these two numbers are 7 * 5 = 35 and 7 * 4 = 28
Ha ha ha, although someone gave the answer, but for the sake of the task, I still.... 28 and 35, sorry

On the least common multiple or the greatest common factor
a. The greatest common factor of two numbers B is 15 and the least common multiple is 90?
You can divide 60, 45 and 180 by a number. What's the maximum number?
The sum of three consecutive odd numbers is 21. What are the greatest common factor and the least common multiple of these three consecutive odd numbers?
From the five books 3.5.12.15 and 30, take out the numbers of each group with multiple relation, and point out the two groups who are whose multiple and whose factor
Add the calculation method
Least common multiple = a * B / greatest common divisor
So 90 = 30 * B / 15
The solution is b = 45

The thinking of solving problems with the greatest common factor and the least common multiple
Consider this: suppose these two numbers are ax and BX respectively
The greatest common factor is x and the least common multiple is ABX
List two equations
ax+bx=60----1
abx-x=220---2
The solution
a=5,b=7,x=5
So the first number is AX = 25
The second number is BX = 35
The real part and imaginary part of the complex number are expressed in English
Real part
Involving only a complex number of which the real part is zero.
Containing a complex number whose real part is zero
Imaginary part
unitOf,relating to,or being the coefficient of the imaginary unit in a complex number.
Of, relating to, or being the coefficient of the imaginary part of a complex number
So the imaginary part will be represented by I
