    What is the Greatest Common Divisor of 4 and 6?

    Answer

    GCF (HCF) of 4 and 6 is
    2

    Common factors: 1, 2

    2 divides both: 4 ÷ 2 = 2, 6 ÷ 2 = 3 — and 2 and 3 share no factor but 1, so no larger number divides both.

    4 = 22

    6 = 2 × 3

    3—3—

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

    GCF = 2
