The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 7821 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 7821 and 2 | 15,642 | 1 | 31,284 |
| 7821 and 3 | 7,821 | 3 | 15,642 |
| 7821 and 4 | 31,284 | 1 | 62,568 |
| 7821 and 5 | 39,105 | 1 | 78,210 |
| 7821 and 6 | 15,642 | 3 | 31,284 |
Start at 7821 and keep adding 7821. That gives 7821, 15642, 23463, 31284, 39105, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 7821 × 7 = 54,747 saves you counting seven hops one at a time.
Because 7821 is odd, its multiples alternate between odd and even. That alternation is a quick way to sanity-check an answer before you write it down.
The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, then back to the start. Spotting that cycle is a fast way to rule out a wrong answer.
The multiples of 7821 are 7821, 15642, 23463, 31284, 39105, 46926, 54747, 62568, 70389, 78210, and so on. Each one is 7821 multiplied by a whole number, so the list continues without end.
7821 is larger than 100, so it has no multiples in that range.
7,821 is greater than 1,000, so its first multiple is already above that range.
The 10th multiple of 7821 is 7821 × 10 = 78,210.
The factors of 7821 are 1, 3, 9, 11, 33, 79, 99, 237, 711, 869, 2607, 7821 — 12 in total. Factors divide into 7821; multiples are built out of it.
