What four numbers multiplied by each other equals 90?
If you want only whole numbers, and they are all different, then: 1 × 2 × 5 × 9 = 90 Otherwise, with whole numbers which are not all different: 1 × 1 × 1 × 90 = 90 1 × 1 × 2 × 45 = 90 1 × 1 × 3 × 30 = 90 1 × 1 × 5 × 18 = 90 1 × 1 × 6 × 15 = 90 1 × 1 × 9 × 10 = 90 1 × 2 × 3 × 15 = 90 1 × 2 × 5 × 9 = 90 1 × 3 × 3 × 10 = 90 1 × 3 × 5 × 6 = 90 2 × 3 × 3 × 5 = 90 Once you start allowing fractions, there are infinitely many such 4 number combinations, eg ½ × 2 × 9 × 10
