Write the sum of 56 + 64 as the product of their GCF and another sum

First, find the GCF, or greatest common factor of 56 and 64.

The GCF of 56 and 64 is 8, because 8 is the square root of 64, and also goes into 56.

56 + 64 = 120

Now, you simply find any sum that, when multiplied by 8, is equal to 120.

The easiest way is to divide 120 by 8 and make a sum of the quotient.

120 : 8 = 15

Therefore, any two factors of fifteen, multiplied by 8, will be your answer.

8 * (1+14)

8 * (2+13)

8 * (3+12)

8 * (4+11)

8 * (5+10)

8 * (6+9)

8 * (7+8)

Any of the seven equations above are correct.
