1605 is larger than 100, so it has no multiples below 100. Its first multiple is 1,605 itself.
1,605 is greater than 1,000, so its first multiple already sits above that range.
Factors are the mirror image of multiples: they divide into 1605 exactly, rather than being built from it. The factors of 1605 are 1, 3, 5, 15, 107, 321, 535, 1605.
Written as pairs: 1 × 1605, 3 × 535, 5 × 321, 15 × 107.
Broken all the way down into primes, 1605 = 3 × 5 × 107.
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 1605 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 1605 and 2 | 3,210 | 1 | 6,420 |
| 1605 and 3 | 1,605 | 3 | 3,210 |
| 1605 and 4 | 6,420 | 1 | 12,840 |
| 1605 and 5 | 1,605 | 5 | 3,210 |
| 1605 and 6 | 3,210 | 3 | 6,420 |
Start at 1605 and keep adding 1605. That gives 1605, 3210, 4815, 6420, 8025, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 1605 × 7 = 11,235 saves you counting seven hops one at a time.
Because 1605 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 1605 always end in 0 or 5, which is why they turn up so often in money and measurement problems.
The multiples of 1605 are 1605, 3210, 4815, 6420, 8025, 9630, 11235, 12840, 14445, 16050, and so on. Each one is 1605 multiplied by a whole number, so the list continues without end.
1605 is larger than 100, so it has no multiples in that range.
1,605 is greater than 1,000, so its first multiple is already above that range.
