How to find the factors of 1116 yourself

Divide 1116 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 √111633.41, because every factor above that pairs with one below it.

1116 ÷ 1 = 1116
1116 ÷ 2 = 558
1116 ÷ 3 = 372
1116 ÷ 4 = 279
1116 ÷ 6 = 186
1116 ÷ 9 = 124
1116 ÷ 12 = 93
1116 ÷ 18 = 62
1116 ÷ 31 = 36

Reading both columns gives every factor: 1, 2, 3, 4, 6, 9, 12, 18, 31, 36, 62, 93, 124, 186, 279, 372, 558, 1116. The factor calculator does this automatically for any number.
