Answer
LCM of 70 and 485 is
6,790
First common multiples: 6,790; 13,580; 20,370; …
6,790 is divisible by both: 6,790 ÷ 70 = 97; 6,790 ÷ 485 = 14 — and 97 and 14 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/70 by 97 and of y/485 by 14.
70 = 2 × 5 × 7
485 = 5 × 97
| Prime | 70 | 485 | Highest power |
|---|---|---|---|
| 2 | 2 | — | 2 |
| 5 | 5 | 5 | 5 |
| 7 | 7 | — | 7 |
| 97 | — | 97 | 97 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
LCM = 2 × 5 × 7 × 97 = 6,790
