What is the GCF of 2, 12 and 16?

What's the Greatest Common Factor (GCF) of 2, 12 and 16?

Answer

GCF of 2, 12 and 16 is

2

Common factors: 1, 2

2 divides all three: 2 ÷ 2 = 1, 12 ÷ 2 = 6, 16 ÷ 2 = 8 — and 1, 6 and 8 have no factor but 1 common to all of them, so no larger number divides all three.

2 — prime

12 = 2² × 3

16 = 2⁴

Prime	2	12	16	Lowest power
2	2	2²	2⁴	2
3	—	3	—	—

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

GCF = 2
