Answer
LCM of 26 and 56 is
728
First common multiples: 728; 1,456; 2,184; …
728 is divisible by both: 728 ÷ 26 = 28, 728 ÷ 56 = 13 — and 28 and 13 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/26 by 28 and of y/56 by 13.
26 = 2 × 13
56 = 23 × 7
| Prime | 26 | 56 | Highest power |
|---|---|---|---|
| 2 | 2 | 23 | 23 |
| 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 = 23 × 7 × 13 = 728
