What's the Least Common Multiple (LCM) of 19 and 49?
Answer
LCM of 19 and 49 is
931
First common multiples: 931; 1,862; 2,793; …
931 is divisible by both: 931 ÷ 19 = 49, 931 ÷ 49 = 19 — and 49 and 19 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/19 by 49 and of y/49 by 19.
19 and 49 are coprime (GCF = 1), so their LCM is simply the product: 19 × 49 = 931.
19 — prime
49 = 72
| Prime | 19 | 49 | Highest power |
|---|---|---|---|
| 7 | — | 72 | 72 |
| 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 = 72 × 19 = 931
