What's the Least Common Multiple (LCM) of 30 and 80?
Answer
LCM of 30 and 80 is
240
First common multiples: 240, 480, 720, …
240 is divisible by both: 240 ÷ 30 = 8, 240 ÷ 80 = 3 — and 8 and 3 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/30 by 8 and of y/80 by 3.
30 = 2 × 3 × 5
80 = 24 × 5
| Prime | 30 | 80 | Highest power |
|---|---|---|---|
| 2 | 2 | 24 | 24 |
| 3 | 3 | — | 3 |
| 5 | 5 | 5 | 5 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 24 × 3 × 5 = 240
