What's the Greatest Common Factor (GCF) of 6, 16 and 24?

Answer

GCF of 6, 16 and 24 is
2

Common factors: 1, 2

2 divides all three: 6 ÷ 2 = 3, 16 ÷ 2 = 8, 24 ÷ 2 = 12 — and 3, 8 and 12 have no factor but 1 common to all of them, so no larger number divides all three.

6 = 2 × 3

16 = 24

24 = 23 × 3

FAQ

What's the Greatest Common Factor (GCF) of 6, 16 and 24?

GCF of 6, 16 and 24 is 2

What prime factors do 6, 16 and 24 share?

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

Can you get the GCF of 6, 16 and 24 two numbers at a time?

Yes. The GCF of 6 and 16 is 2, and the GCF of 2 and 24 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 6 : 16 : 24?

Divide every term by the GCF 2: 6 ÷ 2 = 3, 16 ÷ 2 = 8 and 24 ÷ 2 = 12. So 6 : 16 : 24 in lowest terms is 3 : 8 : 12, and no whole number other than 1 divides all three of those.
