    Answer:

    Decompose the numbers into their prime factors.

    Underline the factors that all the original numbers have in common.

    Multiply the underlined numbers to get the GCF.

    For example:

    Find the greatest common factor of 12 and 20.

    Write down all the factor pairs of 12 and 20:

    Factor pairs of 12: 1 x 12, 2 x 6, 3 x 4

    Factor pairs of 20: 1 x 20, 2 x 10, 4 x 5

    The number 4 is the greatest number that appears in both lists of factor pairs, so it’s the GCF.
