That is 22 multiples of 45 below 1,000, ending at 990.
Factors are the mirror image of multiples: they divide into 45 exactly, rather than being built from it. The factors of 45 are 1, 3, 5, 9, 15, 45.
Written as pairs: 1 × 45, 3 × 15, 5 × 9.
Broken all the way down into primes, 45 = 3² × 5.
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 45 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 45 and 2 | 90 | 1 | 180 |
| 45 and 3 | 45 | 3 | 90 |
| 45 and 4 | 180 | 1 | 360 |
| 45 and 5 | 45 | 5 | 90 |
| 45 and 6 | 90 | 3 | 180 |
Start at 45 and keep adding 45. That gives 45, 90, 135, 180, 225, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 45 × 7 = 315 saves you counting seven hops one at a time.
Because 45 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 45 always end in 0 or 5, which is why they turn up so often in money and measurement problems.
The multiples of 45 are 45, 90, 135, 180, 225, 270, 315, 360, 405, 450, and so on. Each one is 45 multiplied by a whole number, so the list continues without end.
There are 2 multiples of 45 between 1 and 100: 45, 90.
