    What's the Greatest Common Factor (GCF) of 3, 4 and 5?

    Answer

    GCF of 3, 4 and 5 is
    1

    Common factors: 1

    Only 1 divides all three: no prime is a factor of each of 3, 4 and 5.

    The three numbers are pairwise coprime: no two of them share a factor other than 1.

    3 — prime

    4 = 22

    5 — prime

    — = 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 3, 4 and 5?

    GCF of 3, 4 and 5 is 1

    What prime factors do 3, 4 and 5 share?

    None at all: 3, 4 and 5 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 3, 4 and 5 two numbers at a time?

    Yes. The GCF of 3 and 4 is 1, and the GCF of 1 and 5 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 3 : 4 : 5?

    Divide every term by the GCF 1: 3 ÷ 1 = 3, 4 ÷ 1 = 4 and 5 ÷ 1 = 5. So 3 : 4 : 5 in lowest terms is 3 : 4 : 5, and no whole number other than 1 divides all three of those.
