    What is the Greatest Common Divisor of 18 and 36?

    Answer

    GCF of 18 and 36 is
    18

    (Eighteen)

    Finding GCF for 18 and 36 using all factors (divisors) listing

    The first method to find GCF for numbers 18 and 36 is to list all factors for both numbers and pick the highest common one:

    All factors of 18: 1, 2, 3, 6, 9, 18

    All factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

    So the Greatest Common Factor for 18 and 36 is 18

    Finding GCF for 18 and 36 by Prime Factorization

    The second method to find GCF for numbers 18 and 36 is to list all Prime Factors for both numbers and multiply the common ones:

    All Prime Factors of 18: 2, 3, 3

    All Prime Factors of 36: 2, 2, 3, 3

    As we can see there are Prime Factors common to both numbers: 2, 3, 3

    Now we need to multiply them to find GCF: 2 × 3 × 3 = 18
