321, 642, 963
That is 3 multiples of 321 below 1,000, ending at 963.
Factors are the mirror image of multiples: they divide into 321 exactly, rather than being built from it. The factors of 321 are 1, 3, 107, 321.
Written as pairs: 1 × 321, 3 × 107.
Broken all the way down into primes, 321 = 3 × 107.
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 321 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 321 and 2 | 642 | 1 | 1,284 |
| 321 and 3 | 321 | 3 | 642 |
| 321 and 4 | 1,284 | 1 | 2,568 |
| 321 and 5 | 1,605 | 1 | 3,210 |
| 321 and 6 | 642 | 3 | 1,284 |
Start at 321 and keep adding 321. That gives 321, 642, 963, 1284, 1605, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 321 × 7 = 2,247 saves you counting seven hops one at a time.
Because 321 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 321 are 321, 642, 963, 1284, 1605, 1926, 2247, 2568, 2889, 3210, and so on. Each one is 321 multiplied by a whole number, so the list continues without end.
321 is larger than 100, so it has no multiples in that range.
There are 3 multiples of 321 below 1,000. They run from 321 up to 963.
The 10th multiple of 321 is 321 × 10 = 3,210.
The factors of 321 are 1, 3, 107, 321 — 4 in total. Factors divide into 321; multiples are built out of it.
No. 321 is a composite number — it has 4 factors, and breaks down into 3 × 107.
The lowest common multiple of 321 and 2 is 642. It is the first number that appears in both multiplication tables.
