Answer
LCM of 12 and 46 is
276
First common multiples: 276, 552, 828, …
276 is divisible by both: 276 ÷ 12 = 23, 276 ÷ 46 = 6 — and 23 and 6 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/12 by 23 and of y/46 by 6.

46 = 2 × 23

|---|---|---|---|
| 2 | 22 | 2 | 22 |
| 3 | 3 | — | 3 |
| 23 | — | 23 | 23 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
