    What's the Greatest Common Factor (GCF) of 5, 8 and 12?

    Answer

    GCF of 5, 8 and 12 is
    1

    Common factors: 1

    Only 1 divides all three: no prime is a factor of each of 5, 8 and 12.

    Pairs do share factors — GCF(8, 12) = 4 — just none greater than 1 common to all three.

    5 — prime

    8 = 23

    12 = 22 × 3

    — = power 0: the prime is not a factor of this number, so it cannot be in the GCF.

    FAQ

    What's the Greatest Common Factor (GCF) of 5, 8 and 12?

    GCF of 5, 8 and 12 is 1

    What prime factors do 5, 8 and 12 share?

    None at all: 5, 8 and 12 have no prime factor in common, so the only positive integer dividing all three is 1 and their GCF is 1.

    Can you get the GCF of 5, 8 and 12 two numbers at a time?

    Yes. The GCF of 5 and 8 is 1, and the GCF of 1 and 12 is 1 — the same answer, because the greatest common factor is associative and does not depend on the order of the three numbers.

    How does the GCF simplify the ratio 5 : 8 : 12?

    Divide every term by the GCF 1: 5 ÷ 1 = 5, 8 ÷ 1 = 8 and 12 ÷ 1 = 12. So 5 : 8 : 12 in lowest terms is 5 : 8 : 12, and no whole number other than 1 divides all three of those.
