Which 3 numbers x up to 2744?

Answer 1

2744 = 1 x 1 x 2 x 2 x 2 x 7 x 7 x 7

Make 3 groups of these factors and multiply the numbers in each group to get 3 numbers, eg:

{1}, {1}, {2, 2, 2, 7, 7, 7} = 1 x 1 x 2744

{1}, {1, 2}, {2, 2, 7, 7, 7} = 1 x 2 x 1372

{1, 2}, {1, 2, 7}, {2, 7, 7} = 2 x 14 x 98

{1, 2, 7}, {1, 2, 7}, {2, 7} = 14 x 14 x 14
