What is the greatest common factor of 16 and 8?

1 answer

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 16 and 8, we can list the factors of each number:

  • Factors of 16: 1, 2, 4, 8, 16
  • Factors of 8: 1, 2, 4, 8

Now, we find the common factors: 1, 2, 4, and 8. The greatest of these is 8.

Therefore, the greatest common factor of 16 and 8 is 8.
