Question

Use the GCF and distributive property to write 24 + 40 as a product.

For example:
15 + 20
5(3 + 4)

Answer 1

24 + 40 = 8*(3 + 5)

Explanation:

The factors of:

24: 1, 2, 3, 4, 6, 8, 12, 14

40: 1, 2, 4, 5, 8, 10, 20, 40

the prime factors:

24: 2 * 2 * 2 * 3

40: 2 * 2 * 2 * 5

The most shared factors are (2*2*2=8)

Factoring out 8 we have:

24 + 40 = 8*(3 + 5)
