Answer 1

Write both numbers as a product of prime numbers:

• 56=2³·7;
• 96=2³·2²·3.

Then GCF(56,96)=2³=8.

Now you can rewrite the sum 56+96 as following two factors:

56+96=8·7+8·12=8·(7+12)=8·19 (here the first factor os GCF and the secomd factor is  the sum of two numbers 7 and 12 that do not have a common factor).

Answer: 56+96=8·19.
