What's the Least Common Multiple (LCM) of 27 and 36?
Answer
LCM of 27 and 36 is
108
First common multiples: 108, 216, 324, …
108 is divisible by both: 108 ÷ 27 = 4, 108 ÷ 36 = 3 — and 4 and 3 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/27 by 4 and of y/36 by 3.
27 = 33
36 = 22 × 32
| Prime | 27 | 36 | Highest power |
|---|---|---|---|
| 2 | — | 22 | 22 |
| 3 | 33 | 32 | 33 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 22 × 33 = 108
