What is the greatest common multiple of 7 and 56?

Answer 1

The greatest common multiple of two numbers is the smallest number that is a multiple of both numbers. In this case, the multiples of 7 are 7, 14, 21, 28, 35, 42, 49, 56, and so on. The multiples of 56 are 56, 112, 168, 224, and so on. The smallest number that appears in both lists is 56, so the greatest common multiple of 7 and 56 is 56.

Answer 2

56 is a multiple of 7, and 56 is also a multiple of itself, so 56 is

the least common multiple of both numbers.

There is no greatest common multiple. Whatever multiple you name,

no matter how large it is, I can always add 56 to it and come up with

a larger one.

Answer 3

The greatest common multiple of any set of integers is infinite.
