What is the LCM of 48 and 128?

What's the Least Common Multiple (LCM) of 48 and 128?

Answer

LCM of 48 and 128 is

384

First common multiples: 384; 768; 1,152; …

384 is divisible by both: 384 ÷ 48 = 8, 384 ÷ 128 = 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/48 by 8 and of y/128 by 3.

48 = 2⁴ × 3

128 = 2⁷

Prime	48	128	Highest power
2	2⁴	2⁷	2⁷
3	3	—	3

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

LCM = 2⁷ × 3 = 384
