What is the Gcf of 64 and 36

Answer=4

To find the GCF of two numbers, we must first solve for the prime factors of the two numbers.

Prime Factors of 64=2*2*2*2*2*2

Prime Factors of 36=2*2*3*3

The two number have two 2's in common, so the GCF is 2*2 or 4

36: 22 33

64: 222222

GCF = 2*2 = 4.

Thus, the f=greatest common factor of 64 and 36 is 4.
