How to find the factors of 788 yourself

Divide 788 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 √78828.07, because every factor above that pairs with one below it.

788 ÷ 1 = 788
788 ÷ 2 = 394
788 ÷ 4 = 197

Reading both columns gives every factor: 1, 2, 4, 197, 394, 788. The factor calculator does this automatically for any number.
