What's the Least Common Multiple (LCM) of 6 and 27?
Answer
LCM of 6 and 27 is
54
First common multiples: 54, 108, 162, …
54 is divisible by both: 54 ÷ 6 = 9, 54 ÷ 27 = 2 — and 9 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/6 by 9 and of y/27 by 2.
6 = 2 × 3
27 = 33
| Prime | 6 | 27 | Highest power |
|---|---|---|---|

| 3 | 3 | 33 | 33 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 2 × 33 = 54
