How to find the factors of 1122 yourself

Divide 1122 by each whole number starting from 1. Whenever the division leaves no remainder, both the divisor and the quotient are factors. You only need to test up to √112233.50, because every factor above that pairs with one below it.

1122 ÷ 1 = 1122
1122 ÷ 2 = 561
1122 ÷ 3 = 374
1122 ÷ 6 = 187
1122 ÷ 11 = 102
1122 ÷ 17 = 66
1122 ÷ 22 = 51
1122 ÷ 33 = 34

Reading both columns gives every factor: 1, 2, 3, 6, 11, 17, 22, 33, 34, 51, 66, 102, 187, 374, 561, 1122. The factor calculator does this automatically for any number.
