Question

3 children whose ages are the product of 72, what are their ages?

Answer 1

72/3 is 24 and each children can be 24. There are many answers. I would not choose the 24 years old as the answer. instead, I would say one children is 3 another is 3 too and the last one is 12.

Answer 2

There are a lot of combinations that will result to a product of 72. First, let us perform prime factorization on 72.

72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1

1 x 2 x 2 x 2 x 3 x 3 = 72

Age combinations:

1 x 8 x 9 = 72
2 x 4 x 9 = 72
2 x 6 x 6 = 72
3 x 4 x 6 = 72
