What is the greatest common factor of 12 and 37?

Answer 1

To find the Greatest Common Factor (GCF) of 12 and 37, you could list the factors of each and find the one that is greatest that they have in common. In that case, the factors would be:

12: 1, 2, 3, 5, 6, 12

37: 1, 37

the GCF is 1

In this case, though, you shouldn't have to do that. By looking at the numbers, you should notice that 37 is a Prime number and has no factors in common with the number 12, except for 1.
