    The GCF for the variable part is

    k

    Step-by-step explanation:

    Since

    18

    k

    ,

    15

    k

    3

    contain both numbers and variables, there are two steps to find the GCF (HCF). Find GCF for the numeric part then find GCF for the variable part.

    Steps to find the GCF for
