What is the gcf of 12 and 8?

The greatest common factor (GCF) of two numbers is the largest number that divides both of them evenly.

To find the GCF of 12 and 8, we can list the factors of each number:

Factors of 12: 1, 2, 3, 4, 6, 12 Factors of 8: 1, 2, 4, 8

The common factors of 12 and 8 are 1, 2, and 4. The largest of these common factors is 4, so the GCF of 12 and 8 is 4.
