What's the Least Common Multiple (LCM) of 46 and 55?

Answer

LCM of 46 and 55 is
2,530

First common multiples: 2,530; 5,060; 7,590; …

2,530 is divisible by both: 2,530 ÷ 46 = 55; 2,530 ÷ 55 = 46 — and 55 and 46 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/46 by 55 and of y/55 by 46.

46 and 55 are coprime (GCF = 1), so their LCM is simply the product: 46 × 55 = 2,530.

46 = 2 × 23

55 = 5 × 11

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

LCM = 2 × 5 × 11 × 23 = 2,530
