What is the GCF of 6, 8 and 12?

What's the Greatest Common Factor (GCF) of 6, 8 and 12?

Answer

GCF of 6, 8 and 12 is

2

Common factors: 1, 2

2 divides all three: 6 ÷ 2 = 3, 8 ÷ 2 = 4, 12 ÷ 2 = 6 — and 3, 4 and 6 have no factor but 1 common to all of them, so no larger number divides all three.

6 = 2 × 3

8 = 2³

12 = 2² × 3

Prime	6	8	12	Lowest power
2	2	2³	2²	2
3	3	—	3	—

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

GCF = 2
