"Greatest Common Factor of 3 Numbers" Calculator

What's the Greatest Common Factor (GCF) of 6, 12 and 24?

Answer

GCF of 6, 12 and 24 is

Common factors: 1, 2, 3, 6

6 divides all three: 6 ÷ 6 = 1, 12 ÷ 6 = 2, 24 ÷ 6 = 4 — and 1, 2 and 4 have no factor but 1 common to all of them, so no larger number divides all three.

6 = 2 × 3

12 = 2² × 3

24 = 2³ × 3

Prime	6	12	24	Lowest power

FAQ

What's the Greatest Common Factor (GCF) of 6, 12 and 24?

GCF of 6, 12 and 24 is 6

What prime factors do 6, 12 and 24 share?

All three factorizations contain 2 × 3, and multiplying those shared primes gives 6 — exactly the greatest common factor.

Can you get the GCF of 6, 12 and 24 two numbers at a time?

Yes. The GCF of 6 and 12 is 6, and the GCF of 6 and 24 is 6 — 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 : 12 : 24?

Divide every term by the GCF 6: 6 ÷ 6 = 1, 12 ÷ 6 = 2 and 24 ÷ 6 = 4. So 6 : 12 : 24 in lowest terms is 1 : 2 : 4, and no whole number other than 1 divides all three of those.
