What is the LCM of 10, 20 and 35?

What's the Least Common Multiple (LCM) of 10, 20 and 35?

Answer

LCM of 10, 20 and 35 is

140

First common multiples: 140, 280, 420, …

140 is divisible by all three: 140 ÷ 10 = 14, 140 ÷ 20 = 7, 140 ÷ 35 = 4 — and 14, 7 and 4 have no factor but 1 common to all of them, so no smaller number is. As a common denominator: multiply the top and bottom of x/10 by 14 and of y/20 by 7 and of z/35 by 4.

10 = 2 × 5

20 = 2² × 5

35 = 5 × 7

Prime	10	20	35	Highest power
2	2	2²	—	2²
5	5	5	5	5
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 × 5 × 7 = 140
