What's the Least Common Multiple (LCM) of 14 and 55?
Answer
LCM of 14 and 55 is
770
First common multiples: 770; 1,540; 2,310; …
770 is divisible by both: 770 ÷ 14 = 55, 770 ÷ 55 = 14 — and 55 and 14 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/14 by 55 and of y/55 by 14.
14 and 55 are coprime (GCF = 1), so their LCM is simply the product: 14 × 55 = 770.
14 = 2 × 7
55 = 5 × 11
| Prime | 14 | 55 | Highest power |
|---|---|---|---|
| 2 | 2 | — | 2 |
| 5 | — | 5 | 5 |
| 7 | 7 | — | 7 |
| 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 × 5 × 7 × 11 = 770
