How to find the factors of 1108 yourself

Divide 1108 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 √110833.29, because every factor above that pairs with one below it.

1108 ÷ 1 = 1108
1108 ÷ 2 = 554
1108 ÷ 4 = 277

Reading both columns gives every factor: 1, 2, 4, 277, 554, 1108. The factor calculator does this automatically for any number.
