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.
