Factors are the mirror image of multiples: they divide into 644 exactly, rather than being built from it. The factors of 644 are 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644.
Written as pairs: 1 × 644, 2 × 322, 4 × 161, 7 × 92, 14 × 46, 23 × 28.
Broken all the way down into primes, 644 = 2² × 7 × 23.
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 644 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 644 and 2 | 644 | 2 | 1,288 |
| 644 and 3 | 1,932 | 1 | 3,864 |
| 644 and 4 | 644 | 4 | 1,288 |
| 644 and 5 | 3,220 | 1 | 6,440 |
| 644 and 6 | 1,932 | 2 | 3,864 |
Start at 644 and keep adding 644. That gives 644, 1288, 1932, 2576, 3220, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 644 × 7 = 4,508 saves you counting seven hops one at a time.
Because 644 is even, every one of its multiples is even too — you will never find an odd number in this table.
The last digits repeat in a cycle of 5: 4, 8, 2, 6, 0, then back to the start. Spotting that cycle is a fast way to rule out a wrong answer.
The multiples of 644 are 644, 1288, 1932, 2576, 3220, 3864, 4508, 5152, 5796, 6440, and so on. Each one is 644 multiplied by a whole number, so the list continues without end.
644 is larger than 100, so it has no multiples in that range.
