The greatest common factor of 60 and 72 is 12.
The greatest common factor (GCF) is the largest positive integer that divides both numbers without a remainder. One technique to find the GCF is to compare the prime factorizations of the two numbers.
60 = 2*2*3*5 = 2^2*3*5
72 = 2*2*3*6 = 2^2*3*6
One can easily see that 60 and 72 share a multiplier of (2^2*3) = 12. Thus, the GCF of 60 and 72 is 12.
