There are 6 multiples of 15 between 1 and 100.
15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375, 390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, 735, 750, 765, 780, 795, 810, 825, 840, 855, 870, 885, 900, 915, 930, 945, 960, 975, 990
That is 66 multiples of 15 below 1,000, ending at 990.
Factors are the mirror image of multiples: they divide into 15 exactly, rather than being built from it. The factors of 15 are 1, 3, 5, 15.
Written as pairs: 1 × 15, 3 × 5.
Broken all the way down into primes, 15 = 3 × 5.
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 15 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 15 and 2 | 30 | 1 | 60 |
| 15 and 3 | 15 | 3 | 30 |
| 15 and 4 | 60 | 1 | 120 |
| 15 and 5 | 15 | 5 | 30 |
| 15 and 6 | 30 | 3 | 60 |
Start at 15 and keep adding 15. That gives 15, 30, 45, 60, 75, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 15 × 7 = 105 saves you counting seven hops one at a time.
A number is divisible by 15 when it is divisible by both 3 and 5.
Because 15 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 15 always end in 0 or 5, which is why they turn up so often in money and measurement problems.
The multiples of 15 are 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, and so on. Each one is 15 multiplied by a whole number, so the list continues without end.
There are 6 multiples of 15 between 1 and 100: 15, 30, 45, 60, 75, 90.
There are 66 multiples of 15 below 1,000. They run from 15 up to 990.
The 10th multiple of 15 is 15 × 10 = 150.
The factors of 15 are 1, 3, 5, 15 — 4 in total. Factors divide into 15; multiples are built out of it.
No. 15 is a composite number — it has 4 factors, and breaks down into 3 × 5.
The lowest common multiple of 15 and 2 is 30. It is the first number that appears in both multiplication tables.
