    What is the Greatest Common Divisor of 210 and 300?

    Answer

    GCF of 210 and 300 is
    30

    (Thirty)

    Finding GCF for 210 and 300 using all factors (divisors) listing

    The first method to find GCF for numbers 210 and 300 is to list all factors for both numbers and pick the highest common one:

    All factors of 210: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

    All factors of 300: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300

    So the Greatest Common Factor for 210 and 300 is 30

    Finding GCF for 210 and 300 by Prime Factorization

    The second method to find GCF for numbers 210 and 300 is to list all Prime Factors for both numbers and multiply the common ones:

    All Prime Factors of 210: 2, 3, 5, 7

    All Prime Factors of 300: 2, 2, 3, 5, 5

    As we can see there are Prime Factors common to both numbers: 2, 3, 5

    Now we need to multiply them to find GCF: 2 × 3 × 5 = 30
