Short answer: There are none.

There is neither a greatest common factor nor common factors of a single number, such as 13, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.

The factors of 13 are 1 and 13.

Examples:

The common factors of 13 and 25 are only 1; the greatest common factor is 1.

The common factors of 13 and 52 are 1 and 13; the greatest common factor is 13.
