9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99
There are 11 multiples of 9 between 1 and 100.
9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, … , 981, 990, 999
That is 111 multiples of 9 below 1,000, ending at 999.
Factors are the mirror image of multiples: they divide into 9 exactly, rather than being built from it. The factors of 9 are 1, 3, 9.
Written as pairs: 1 × 9, 3 × 3.
Broken all the way down into primes, 9 = 3².
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 9 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 9 and 2 | 18 | 1 | 36 |
| 9 and 3 | 9 | 3 | 18 |
| 9 and 4 | 36 | 1 | 72 |
| 9 and 5 | 45 | 1 | 90 |
| 9 and 6 | 18 | 3 | 36 |
Start at 9 and keep adding 9. That gives 9, 18, 27, 36, 45, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 9 × 7 = 63 saves you counting seven hops one at a time.
A number is divisible by 9 when the sum of its digits is divisible by 9.
Because 9 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: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, then back to the start. Spotting that cycle is a fast way to rule out a wrong answer.
The multiples of 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, and so on. Each one is 9 multiplied by a whole number, so the list continues without end.
There are 11 multiples of 9 between 1 and 100: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.
There are 111 multiples of 9 below 1,000. They run from 9 up to 999.
The 10th multiple of 9 is 9 × 10 = 90.
The factors of 9 are 1, 3, 9 — 3 in total. Factors divide into 9; multiples are built out of it.
No. 9 is a composite number — it has 3 factors, and breaks down into 3².
The lowest common multiple of 9 and 2 is 18. It is the first number that appears in both multiplication tables.
