How to find the factors of 190 yourself
Divide 190 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 √190 ≈ 13.78, because every factor above that pairs with one below it.
Reading both columns gives every factor: 1, 2, 5, 10, 19, 38, 95, 190. The factor calculator does this automatically for any number.
