Best Answer

The GCF of 8 and 20 is 4

8 = 2 x 2 x 2

20 = 2 x 2 x 5

There are 2 twos in each so 2 x 2 = 4

The GCF is 4.

Another explanation:

The factors of 8 are 1, 2, 4, and 8.

The factors of 20 are 1, 2, 4, 5, 10, and 20.

The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.
The GCF is 4.
