The concept of factors (and common factors) is applicable to whole numbers, not to fractions. The numerator and denominator of a rational fraction are integers and they can have a greatest common factor but that is not a factor of the fraction.

When do you use greatest common factor?

In order to simplify a rational fraction, you can divide the numerator and denominator by their greatest common factor. However, it is often simpler to divide them both by any common factor (not necessarily the greatest) and then to repeat the process with the resulting fraction. This can be just as fast as finding a large common factor and then carrying out divisions using a large number.
