How to find the factors of 1178 yourself

Divide 1178 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 √117834.32, because every factor above that pairs with one below it.

1178 ÷ 1 = 1178
1178 ÷ 2 = 589
1178 ÷ 19 = 62
1178 ÷ 31 = 38

Reading both columns gives every factor: 1, 2, 19, 31, 38, 62, 589, 1178. The factor calculator does this automatically for any number.
