What is the Greatest Common Divisor of 40 and 265?

Answer

GCF (HCF) of 40 and 265 is

5

Common factors: 1, 5

5 divides both: 40 ÷ 5 = 8, 265 ÷ 5 = 53 — and 8 and 53 share no factor but 1, so no larger number divides both.

40 = 2³ × 5

265 = 5 × 53

Prime	40	265	Lowest power
2	2³	—	—
5	5	5	5
53	—	53	—

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

GCF = 5
