Question

How of you find the factors of 109?

Answer 1

`109` does not have any factor.

Explanation:

To find factors of a number we should try dividing it by a prime number up to roughly square root of the number.

As square root of `109` is between `10` and `11` (as their square is `100` and `121`), we can try numbers `{2,3,5,7}`.

AS it is not divisible by any of these numbers, it is a prime numbers and we do not have its factors other than `1` and itself i.e. `109`.
