    1

    (One)

    Finding GCF for 4 and 15 using all factors (divisors) listing

    The first method to find GCF for numbers 4 and 15 is to list all factors for both numbers and pick the highest common one:

    All factors of 4: 1, 2, 4

    All factors of 15: 1, 3, 5, 15

    So the Greatest Common Factor for 4 and 15 is 1

    Finding GCF for 4 and 15 by Prime Factorization

    The numbers 4 and 15 have no common prime factors, which means they are coprime (relatively prime). Therefore, GCF = 1.
