    Answer

    GCF of 16, 20 and 27 is
    1

    Common factors: 1

    Only 1 divides all three: no prime is a factor of each of 16, 20 and 27.

    Pairs do share factors — GCF(16, 20) = 4 — just none greater than 1 common to all three.

    16 = 24

    20 = 22 × 5

    27 = 33

    FAQ

    What's the Greatest Common Factor (GCF) of 16, 20 and 27?

    GCF of 16, 20 and 27 is 1

    What prime factors do 16, 20 and 27 share?

    None at all: 16, 20 and 27 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 16, 20 and 27 two numbers at a time?

    Yes. The GCF of 16 and 20 is 4, and the GCF of 4 and 27 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 16 : 20 : 27?

    Divide every term by the GCF 1: 16 ÷ 1 = 16, 20 ÷ 1 = 20 and 27 ÷ 1 = 27. So 16 : 20 : 27 in lowest terms is 16 : 20 : 27, and no whole number other than 1 divides all three of those.
