Question

Use the greatest common factor of 84 and 48 to write the sum 84+48 as a product. Write a whole number in each black.​

Answer 1

Answer: Below

Explanation:

Looking at the numbers, they already seem to be multiples of fours. If we try to scale four up, 12 is the next biggest factor.
84 = 12 * 7
48 = 12 * 4
7 + 4 = 13
12 * 13 = 84 * 48
12 * 13 = 132
