What is the greatest common factor of 120 and 64?

Answer 1

A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.

One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.

The factors of 64 are 1, 2, 4, 8, 16, 32, and 64.

The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.

The common factors are 1, 2, 4, and 8. Therefore, the greatest common factor is 8.

Answer 2

The greatest common factor (GCF) of 64 and 120 is 8.

Answer 3

The GCF is 32.
