What's the Least Common Multiple (LCM) of 56 and 90?
Answer
LCM of 56 and 90 is
2,520
First common multiples: 2,520; 5,040; 7,560; …
2,520 is divisible by both: 2,520 ÷ 56 = 45; 2,520 ÷ 90 = 28 — and 45 and 28 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/56 by 45 and of y/90 by 28.
56 = 23 × 7
90 = 2 × 32 × 5
| Prime | 56 | 90 | Highest power |
|---|---|---|---|
| 2 | 23 | 2 | 23 |
| 3 | — | 32 | 32 |
| 5 | — | 5 | 5 |
| 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 = 23 × 32 × 5 × 7 = 2,520
