What is the LCM of 50 and 140?

What's the Least Common Multiple (LCM) of 50 and 140?

Answer

LCM of 50 and 140 is

700

First common multiples: 700; 1,400; 2,100; …

700 is divisible by both: 700 ÷ 50 = 14, 700 ÷ 140 = 5 — and 14 and 5 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/50 by 14 and of y/140 by 5.

50 = 2 × 5²

140 = 2² × 5 × 7

Prime	50	140	Highest power
2	2	2²	2²
5	5²	5	5²
7	—	7	7

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

LCM = 2² × 5² × 7 = 700
