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

Answer

GCF of 18, 32 and 48 is

2

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
