What is the Greatest Common Divisor of 50 and 51?

Answer

GCF (HCF) of 50 and 51 is

1

Common factors: 1

Only 1 divides both: 50 and 51 share no prime factor.

Such numbers are called coprime (relatively prime); their LCM is just the product: 50 × 51 = 2,550.

50 = 2 × 5²

51 = 3 × 17

Prime	50	51	Lowest power
2	2	—	—
3	—	3	—
5	5²	—	—
17	—	17	—

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

GCF = 1
