Answer
LCM of 80 and 475 is
7,600
First common multiples: 7,600; 15,200; 22,800; …
7,600 is divisible by both: 7,600 ÷ 80 = 95; 7,600 ÷ 475 = 16 — and 95 and 16 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/80 by 95 and of y/475 by 16.
80 = 24 × 5
475 = 52 × 19

|---|---|---|---|
| 2 | 24 | — | 24 |
| 5 | 5 | 52 | 52 |
| 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 = 24 × 52 × 19 = 7,600
