What is the LCM of 10 and 99?

What's the Least Common Multiple (LCM) of 10 and 99?

Answer

LCM of 10 and 99 is

990

First common multiples: 990; 1,980; 2,970; …

990 is divisible by both: 990 ÷ 10 = 99, 990 ÷ 99 = 10 — and 99 and 10 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/10 by 99 and of y/99 by 10.

10 and 99 are coprime (GCF = 1), so their LCM is simply the product: 10 × 99 = 990.

10 = 2 × 5

99 = 3² × 11

Prime	10	99	Highest power
2	2	—	2
3	—	3²	3²
5	5	—	5
11	—	11	11

— = 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 × 11 = 990
