    What's the Greatest Common Factor (GCF) of 4, 6 and 12?

    Answer

    GCF of 4, 6 and 12 is
    2

    Common factors: 1, 2

    2 divides all three: 4 ÷ 2 = 2, 6 ÷ 2 = 3, 12 ÷ 2 = 6 — and 2, 3 and 6 have no factor but 1 common to all of them, so no larger number divides all three.

    4 = 22

    6 = 2 × 3

    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 4, 6 and 12?

    GCF of 4, 6 and 12 is 2

    What prime factors do 4, 6 and 12 share?

    All three factorizations contain 2, and multiplying those shared primes gives 2 — exactly the greatest common factor.

    Can you get the GCF of 4, 6 and 12 two numbers at a time?

    Yes. The GCF of 4 and 6 is 2, and the GCF of 2 and 12 is 2 — 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 4 : 6 : 12?

    Divide every term by the GCF 2: 4 ÷ 2 = 2, 6 ÷ 2 = 3 and 12 ÷ 2 = 6. So 4 : 6 : 12 in lowest terms is 2 : 3 : 6, and no whole number other than 1 divides all three of those.
