    Answer

    GCF of 35 and 70 is
    35

    (Thirty-five)

    Finding GCF for 35 and 70 using all factors (divisors) listing

    The first method to find GCF for numbers 35 and 70 is to list all factors for both numbers and pick the highest common one:

    All factors of 35: 1, 5, 7, 35

    All factors of 70: 1, 2, 5, 7, 10, 14, 35, 70

    So the Greatest Common Factor for 35 and 70 is 35

    Finding GCF for 35 and 70 by Prime Factorization

    The second method to find GCF for numbers 35 and 70 is to list all Prime Factors for both numbers and multiply the common ones:

    All Prime Factors of 35: 5, 7

    All Prime Factors of 70: 2, 5, 7
