Question

Find the greatest common factor of 40 and 16, then use the GCF to factory 40 + 16.

Answer 1

The GCF is 8 ; factored is 8(5+2)

Explanation:

The gcf of 40 and 16 is 8.

Since 8*5 = 40 and 8*2 = 16:

40+16 = 8(5+2).

Answer 2

The GCF of 16 and 40 is 8. To calculate the greatest common factor of 16 and 40, we need to factor each number (factors of 16 = 1, 2, 4, 8, 16; factors of 40 = 1, 2, 4, 5, 8, 10, 20, 40) and choose the greatest factor that exactly divides both 16 and 40, i.e., 8.
