    What is the Greatest Common Divisor of 270 and 900?

    Answer

    GCF of 270 and 900 is
    90

    (Ninety)

    Finding GCF for 270 and 900 using all factors (divisors) listing

    The first method to find GCF for numbers 270 and 900 is to list all factors for both numbers and pick the highest common one:

    All factors of 270: 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

    All factors of 900: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

    So the Greatest Common Factor for 270 and 900 is 90

    Finding GCF for 270 and 900 by Prime Factorization

    The second method to find GCF for numbers 270 and 900 is to list all Prime Factors for both numbers and multiply the common ones:

    All Prime Factors of 270: 2, 3, 3, 3, 5

    All Prime Factors of 900: 2, 2, 3, 3, 5, 5
