What's the Least Common Multiple (LCM) of 60 and 215?
Answer
LCM of 60 and 215 is
2,580
First common multiples: 2,580; 5,160; 7,740; …
2,580 is divisible by both: 2,580 ÷ 60 = 43; 2,580 ÷ 215 = 12 — and 43 and 12 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/60 by 43 and of y/215 by 12.
60 = 22 × 3 × 5
215 = 5 × 43
| Prime | 60 | 215 | Highest power |
|---|---|---|---|
| 2 | 22 | — | 22 |
| 3 | 3 | — | 3 |
| 5 | 5 | 5 | 5 |
| 43 | — | 43 | 43 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 22 × 3 × 5 × 43 = 2,580
