What is the Greatest Common Divisor of 40 and 63?

Answer

GCF (HCF) of 40 and 63 is

Common factors: 1

Only 1 divides both: 40 and 63 share no prime factor.

Such numbers are called coprime (relatively prime); their LCM is just the product: 40 × 63 = 2,520.

40 = 2³ × 5

63 = 3² × 7

Prime	40	63	Lowest power
2	2³	—	—
3	—	3²	—
5	5	—	—
7	—	7	—

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

GCF = 1
