Question

Using the greatest common factor for the terms, how can you write 45 + 75 as a product?

Answer 1

Biggest division is 15

45÷15 = 3

75÷15 = 5

15(3+5)

Answer 2

15(3 + 5)

Explanation:

The GCF is the greatest common number that multiplies into both terms. Here it is 15. So 45 + 75 becomes 15(3 + 5).
