What's the Least Common Multiple (LCM) of 25 and 20?
Answer
LCM of 25 and 20 is
100
First common multiples: 100, 200, 300, …
100 is divisible by both: 100 ÷ 25 = 4, 100 ÷ 20 = 5 — and 4 and 5 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/25 by 4 and of y/20 by 5.
25 = 52
20 = 22 × 5
| Prime | 25 | 20 | Highest power |
|---|---|---|---|
| 2 | — | 22 | 22 |
| 5 | 52 | 5 | 52 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 22 × 52 = 100
