Answer
LCM of 17 and 27 is
459
First common multiples: 459; 918; 1,377; …
459 is divisible by both: 459 ÷ 17 = 27, 459 ÷ 27 = 17 — and 27 and 17 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/17 by 27 and of y/27 by 17.
17 and 27 are coprime (GCF = 1), so their LCM is simply the product: 17 × 27 = 459.

27 = 33
| Prime | 17 | 27 | Highest power |
|---|---|---|---|
| 3 | — | 33 | 33 |
| 17 | 17 | — | 17 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 33 × 17 = 459
