    What is the Greatest Common Divisor of 1,152 and 1,664?

    Answer

    GCF of 1,152 and 1,664 is
    128

    (One hundred twenty-eight)

    Finding GCF for 1,152 and 1,664 using all factors (divisors) listing

    The first method to find GCF for numbers 1,152 and 1,664 is to list all factors for both numbers and pick the highest common one:

    All factors of 1,152: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 128, 144, 192, 288, 384, 576, 1152

    All factors of 1,664: 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 128, 208, 416, 832, 1664

    So the Greatest Common Factor for 1,152 and 1,664 is 128

    Finding GCF for 1,152 and 1,664 by Prime Factorization

    The second method to find GCF for numbers 1,152 and 1,664 is to list all Prime Factors for both numbers and multiply the common ones:

    All Prime Factors of 1,152: 2, 2, 2, 2, 2, 2, 2, 3, 3

    All Prime Factors of 1,664: 2, 2, 2, 2, 2, 2, 2, 13

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