What is the LCM of 2 and 43?

What's the Least Common Multiple (LCM) of 2 and 43?

Answer

LCM of 2 and 43 is

86

First common multiples: 86, 172, 258, …

86 is divisible by both: 86 ÷ 2 = 43, 86 ÷ 43 = 2 — and 43 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/2 by 43 and of y/43 by 2.

2 and 43 are coprime (GCF = 1), so their LCM is simply the product: 2 × 43 = 86.

2 — prime

43 — prime

Prime	2	43	Highest power
2	2	—	2
43	—	43	43

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

LCM = 2 × 43 = 86
