What is the GCF of 2, 4 and 6?

What's the Greatest Common Factor (GCF) of 2, 4 and 6?

Answer

GCF of 2, 4 and 6 is

2

Common factors: 1, 2

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

2 — prime

4 = 2²

6 = 2 × 3

Prime	2	4	6	Lowest power
2	2	2²	2	2
3	—	—	3	—

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

GCF = 2
