What is the LCM of 1 and 8?

What's the Least Common Multiple (LCM) of 1 and 8?

Answer

LCM of 1 and 8 is

8

First common multiples: 8, 16, 24, …

1 divides every number: the GCF with 1 is always 1, and the LCM is the other number itself — here 8.

1 — no prime factors

8 = 2³

Prime	1	8	Highest power
2	—	2³	2³

— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.

LCM = 2³ = 8
