What's the Least Common Multiple (LCM) of 13 and 35?
Answer
LCM of 13 and 35 is
455
First common multiples: 455; 910; 1,365; …
455 is divisible by both: 455 ÷ 13 = 35, 455 ÷ 35 = 13 — and 35 and 13 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/13 by 35 and of y/35 by 13.
13 and 35 are coprime (GCF = 1), so their LCM is simply the product: 13 × 35 = 455.
13 — prime
35 = 5 × 7
| Prime | 13 | 35 | Highest power |
|---|---|---|---|
| 5 | — | 5 | 5 |
| 7 | — | 7 | 7 |
| 13 | 13 | — | 13 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 5 × 7 × 13 = 455
