Answer
LCM of 38 and 39 is
1,482
First common multiples: 1,482; 2,964; 4,446; …
1,482 is divisible by both: 1,482 ÷ 38 = 39; 1,482 ÷ 39 = 38 — and 39 and 38 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/38 by 39 and of y/39 by 38.
38 and 39 are coprime (GCF = 1), so their LCM is simply the product: 38 × 39 = 1,482.
38 = 2 × 19
39 = 3 × 13
| Prime | 38 | 39 | Highest power |
|---|---|---|---|
| 2 | 2 | — | 2 |
| 3 | — | 3 | 3 |
| 13 | — | 13 | 13 |
| 19 | 19 | — | 19 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 2 × 3 × 13 × 19 = 1,482
