What is the Greatest Common Divisor of 2 and 49?

Answer

GCF (HCF) of 2 and 49 is

1

Common factors: 1

Only 1 divides both: 2 and 49 share no prime factor.

Such numbers are called coprime (relatively prime); their LCM is just the product: 2 × 49 = 98.

2 — prime

49 = 7²

Prime	2	49	Lowest power
2	2	—	—
7	—	7²	—

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

GCF = 1
