    10

    (Ten)

    Finding GCF for 80 and 330 using all factors (divisors) listing

    The first method to find GCF for numbers 80 and 330 is to list all factors for both numbers and pick the highest common one:

    All factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

    All factors of 330: 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

    So the Greatest Common Factor for 80 and 330 is 10

    Finding GCF for 80 and 330 by Prime Factorization

    The second method to find GCF for numbers 80 and 330 is to list all Prime Factors for both numbers and multiply the common ones:

    All Prime Factors of 80: 2, 2, 2, 2, 5

    All Prime Factors of 330: 2, 3, 5, 11

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

    Now we need to multiply them to find GCF: 2 × 5 = 10
