What's the Least Common Multiple (LCM) of 18 and 48?

Answer

LCM of 18 and 48 is

144

First common multiples: 144, 288, 432, …

144 is divisible by both: 144 ÷ 18 = 8, 144 ÷ 48 = 3 — and 8 and 3 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/18 by 8 and of y/48 by 3.

18 = 2 × 3²

48 = 2⁴ × 3

Prime	18	48	Highest power
2	2	2⁴	2⁴
3	3²	3	3²

LCM = 2⁴ × 3² = 144
