Write the sum of the numbers as the product of their GCF and anothet sum. Problem: 56+64=?

It looks like the first thing you have to find is their GCF, ya reckon?

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) < = = that's the answer

Check it out:

56 plus 64 = 120

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