What are the greatest common divisor and the least common multiple of 12 and 14? Is it the same as the greatest common divisor of 200 and 350?
The greatest common divisor of 12 and 14 is 2 and the least common multiple is 84
The greatest common factor of 84 and 210
84=21*2*2
210=21*2*5
The greatest common factor of 84 and 210 is 42
What are the greatest common divisor and the least common multiple of 9 and 28, and the greatest common divisor and the least common multiple of 24?
24 and 30
The greatest common divisor of 9 and 28 is 1, and the least common multiple is 252
The greatest common divisor of 24 and 30 is 2 and the least common multiple is 180
What percentage of its least common multiple is the greatest common divisor of 12 and 8
16.67%
The greatest common divisor is 4 and the least common multiple is 24
At least one of the two coprime numbers is prime
Wrong
Coprime means that two numbers have no common factor except one
Because two prime numbers must be coprime numbers, two coprime numbers must be prime numbers______ (judge right or wrong)
According to the meaning of Coprime number, because two different prime numbers are coprime numbers, the two numbers of Coprime are not necessarily prime numbers. For example, 8 and 15 are coprime numbers, both of them are composite numbers; 11 and 12 are coprime numbers, 11 are prime numbers, 12 are composite numbers, so the original statement is wrong
If the greatest common factor of two combined numbers is 3 and the least common multiple is 30, then the two numbers are:______ .
30 × 3 = 90, because 90 = 6 × 15, so the two numbers are 6 and 15 respectively; so the answer is: 6 and 15
Two numbers are composite numbers and coprime numbers. Their least common multiple is 120. What is the greatest common factor of these two numbers, and what is the smallest composite number
These two numbers may be 15 and 8, the greatest common factor is 1, because they are coprime numbers, and the smallest prime number is 2
Two numbers are compound numbers and coprime numbers. Their least common multiple is 120. The greatest common divisor of these two numbers is______ Where the smaller sum is______ .
120 = 2 × 2 × 2 × 3 × 5, two numbers are combined, so these two numbers should be 2 × 2 × 2 and 3 × 5, that is, 8 and 15. These two numbers are coprime numbers, so the greatest common divisor of these two numbers is 1
The greatest common factor is two composite numbers of 1, and their least common multiple is 24
Is there no right answer
