What's the Least Common Multiple (LCM) of 10 and 310?

Answer

LCM of 10 and 310 is

310

First common multiples: 310, 620, 930, …

As a common denominator: multiply the top and bottom of x/10 by 31.

10 divides 310 (310 ÷ 10 = 31), so the LCM is the larger number itself.

10 = 2 × 5

310 = 2 × 5 × 31

Prime	10	310	Highest power
2	2	2	2
5	5	5	5
31	—	31	31

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

LCM = 2 × 5 × 31 = 310
