What is the sum of the numbers 56 and 64 of their gcf and another sum written down

40. We are looking for the sum of the 2 numbers: 56 + 64

But we need to find first their GCF:

Find for the GCF of 56 and 64

Factors of 56 = > 1, 2, 4, 7, 8, 13, 28, 56

Factors of 64 = > 1, 2, 4, 8, 16, 32, 64

In the given factors, let’s find the common factors of both numbers:

=> 1, 2, 4, 8,

Thus, the Greatest common factor of both numbers is 8.

=> 56 / 8 = 7

=> 64 / 8 = 8

Now, let’s find the sum:

=> 56 + 64 = 120

Other sum:

=> 8 (7 + 8)

=> 8 (15)

=> 120
