What is the greatest common factor of 12 and 16?

The greatest common factor (GCF) of two numbers is the largest number that divides both of them without leaving a remainder.

To find the GCF of 12 and 16, we can first determine the factors of each number:

Factors of 12: 1, 2, 3, 4, 6, 12 Factors of 16: 1, 2, 4, 8, 16

The common factors of 12 and 16 are 1, 2, and 4. The largest number among these common factors is 4, so the greatest common factor of 12 and 16 is 4.
