The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 643 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 643 and 2 | 1,286 | 1 | 2,572 |
| 643 and 3 | 1,929 | 1 | 3,858 |
| 643 and 4 | 2,572 | 1 | 5,144 |
| 643 and 5 | 3,215 | 1 | 6,430 |
