What is the LCM of 105 and 126?

What's the Least Common Multiple (LCM) of 105 and 126?

Answer

LCM of 105 and 126 is

630

First common multiples: 630; 1,260; 1,890; …

630 is divisible by both: 630 ÷ 105 = 6, 630 ÷ 126 = 5 — and 6 and 5 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/105 by 6 and of y/126 by 5.

105 = 3 × 5 × 7

126 = 2 × 3² × 7

Prime	105	126	Highest power
2	—	2	2
3	3	3²	3²
5	5	—	5
7	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 = 2 × 3² × 5 × 7 = 630
