### What is the greatest common factor of 12 and 37?

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

more numbers are all the factors that the numbers have in common.
The greatest common factor of two or more numbers is the largest
factor that the numbers have in common.
Methods:
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 74 are 1, 2, 37, and 74.
The factors of 111 are 1, 3, 37, and 111.

the common prime factors and multiplying them together.
The prime factors of 74 are 2 and 37.
The prime factors of 111 are 3 and 37.
The prime factors in common are a single 37, so the greatest
common factor is 37.
The GCF is: 37
