Factor the sum of terms as a product of the GCF and a sum 52 + 28

The factors of 56 are 1, 2, 4, 7, 8, 13, 28, and 56.

The factors of 64 are 1, 2, 4, 8, 16, 32, and 64.

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

The greatest one is 8.

56/8 = 7

64/8 = 8

56 plus 64 = (8 times 7) plus (8 times 8)

56 plus 64 = 8 times (7 plus 8)

Check it out:

56 plus 64 = 120

8 times (7 plus 8) = 8 times 15 = 120
