LCM of 80 and 130 is
1,040
First common multiples: 1,040; 2,080; 3,120; …
1,040 is divisible by both: 1,040 ÷ 80 = 13; 1,040 ÷ 130 = 8 — and 13 and 8 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/80 by 13 and of y/130 by 8.
80 = 24 × 5
130 = 2 × 5 × 13

|---|---|---|---|
| 2 | 24 | 2 | 24 |
| 5 | 5 | 5 | 5 |
| 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 = 24 × 5 × 13 = 1,040
