What's the Least Common Multiple (LCM) of 80 and 325?
Answer
LCM of 80 and 325 is
5,200
First common multiples: 5,200; 10,400; 15,600; …
5,200 is divisible by both: 5,200 ÷ 80 = 65; 5,200 ÷ 325 = 16 — and 65 and 16 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/80 by 65 and of y/325 by 16.
80 = 24 × 5
325 = 52 × 13
| Prime | 80 | 325 | Highest power |
|---|---|---|---|
| 2 | 24 | — | 24 |
| 5 | 5 | 52 | 52 |
| 13 | — | 13 | 13 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 24 × 52 × 13 = 5,200
