Factors are the mirror image of multiples: they divide into 255 exactly, rather than being built from it. The factors of 255 are 1, 3, 5, 15, 17, 51, 85, 255.
Written as pairs: 1 × 255, 3 × 85, 5 × 51, 15 × 17.
Broken all the way down into primes, 255 = 3 × 5 × 17.
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 255 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 255 and 2 | 510 | 1 | 1,020 |
| 255 and 3 | 255 | 3 | 510 |
| 255 and 4 | 1,020 | 1 | 2,040 |
| 255 and 5 | 255 | 5 | 510 |
| 255 and 6 | 510 | 3 | 1,020 |
Start at 255 and keep adding 255. That gives 255, 510, 765, 1020, 1275, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 255 × 7 = 1,785 saves you counting seven hops one at a time.
Because 255 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.
Multiples of 255 always end in 0 or 5, which is why they turn up so often in money and measurement problems.
The multiples of 255 are 255, 510, 765, 1020, 1275, 1530, 1785, 2040, 2295, 2550, and so on. Each one is 255 multiplied by a whole number, so the list continues without end.
255 is larger than 100, so it has no multiples in that range.
There are 3 multiples of 255 below 1,000. They run from 255 up to 765.
The 10th multiple of 255 is 255 × 10 = 2,550.
The factors of 255 are 1, 3, 5, 15, 17, 51, 85, 255 — 8 in total. Factors divide into 255; multiples are built out of it.
No. 255 is a composite number — it has 8 factors, and breaks down into 3 × 5 × 17.
The lowest common multiple of 255 and 2 is 510. It is the first number that appears in both multiplication tables.
