What three numbers multiplied together make 245?

Answer 1

Assuming you want whole numbers, start looking for obvious factors. In this case, since the number ends with 5, 5 is a factor. Divide the number by 5 to get the other factor. Continue looking for small factors, to further split it up.

Answer 2

1 × 1 × 245

1 × 5 × 49

1 × 7 × 35

5 × 7 × 7

Answer 3

There are infinitely many triplets. One such is (2, 5, 24.5).
