What is the Greatest Common Divisor of 10 and 13?

Answer

GCF (HCF) of 10 and 13 is

Common factors: 1

Only 1 divides both: 10 and 13 share no prime factor.

Such numbers are called coprime (relatively prime); their LCM is just the product: 10 × 13 = 130.

10 = 2 × 5

13 — prime

Prime	10	13	Lowest power
2	2	—	—
5	5	—	—
13	—	13	—

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

GCF = 1
