What is the Greatest Common Divisor of 11 and 12?

Answer

GCF (HCF) of 11 and 12 is

Common factors: 1

Only 1 divides both: 11 and 12 share no prime factor.

Such numbers are called coprime (relatively prime); their LCM is just the product: 11 × 12 = 132.

11 — prime

12 = 2² × 3

Prime	11	12	Lowest power
2	—	2²	—
3	—	3	—
11	11	—	—

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

GCF = 1
