What's the Greatest Common Factor (GCF) of 18, 32 and 48?

Answer

GCF of 18, 32 and 48 is

Common factors: 1, 2

2 divides all three: 18 ÷ 2 = 9, 32 ÷ 2 = 16, 48 ÷ 2 = 24 — and 9, 16 and 24 have no factor but 1 common to all of them, so no larger number divides all three.

18 = 2 × 3²

32 = 2⁵

48 = 2⁴ × 3

Prime	18	32	48	Lowest power
2	2	2⁵	2⁴	2
3	3²	—	3	—

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

GCF = 2

FAQ

What's the Greatest Common Factor (GCF) of 18, 32 and 48?

GCF of 18, 32 and 48 is 2

What prime factors do 18, 32 and 48 share?

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

Can you get the GCF of 18, 32 and 48 two numbers at a time?

Yes. The GCF of 18 and 32 is 2, and the GCF of 2 and 48 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 18 : 32 : 48?

Divide every term by the GCF 2: 18 ÷ 2 = 9, 32 ÷ 2 = 16 and 48 ÷ 2 = 24. So 18 : 32 : 48 in lowest terms is 9 : 16 : 24, and no whole number other than 1 divides all three of those.
