1680 is larger than 100, so it has no multiples below 100. Its first multiple is 1,680 itself.
1,680 is greater than 1,000, so its first multiple already sits above that range.
Factors are the mirror image of multiples: they divide into 1680 exactly, rather than being built from it. The factors of 1680 are 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 16, 20, 21, 24, 28, 30, 35, 40, 42, 48, 56, 60, 70, 80, 84, 105, 112, 120, 140, 168, 210, 240, 280, 336, 420, 560, 840, 1680.
Written as pairs: 1 × 1680, 2 × 840, 3 × 560, 4 × 420, 5 × 336, 6 × 280, 7 × 240, 8 × 210, 10 × 168, 12 × 140, 14 × 120, 15 × 112, 16 × 105, 20 × 84, 21 × 80, 24 × 70, 28 × 60, 30 × 56, 35 × 48, 40 × 42.
Broken all the way down into primes, 1680 = 2⁴ × 3 × 5 × 7.
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 1680 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 1680 and 2 | 1,680 | 2 | 3,360 |
| 1680 and 3 | 1,680 | 3 | 3,360 |
| 1680 and 4 | 1,680 | 4 | 3,360 |
| 1680 and 5 | 1,680 | 5 | 3,360 |
| 1680 and 6 | 1,680 | 6 | 3,360 |
Start at 1680 and keep adding 1680. That gives 1680, 3360, 5040, 6720, 8400, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 1680 × 7 = 11,760 saves you counting seven hops one at a time.
Because 1680 is even, every one of its multiples is even too — you will never find an odd number in this table.
Multiples of 1680 always end in 0 or 5, which is why they turn up so often in money and measurement problems.
The multiples of 1680 are 1680, 3360, 5040, 6720, 8400, 10080, 11760, 13440, 15120, 16800, and so on. Each one is 1680 multiplied by a whole number, so the list continues without end.
1680 is larger than 100, so it has no multiples in that range.
1,680 is greater than 1,000, so its first multiple is already above that range.
The 10th multiple of 1680 is 1680 × 10 = 16,800.
The factors of 1680 are 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 16, 20, 21, 24, 28, 30, 35, 40, 42, 48, 56, 60, 70, 80, 84, 105, 112, 120, 140, 168, 210, 240, 280, 336, 420, 560, 840, 1680 — 40 in total. Factors divide into 1680; multiples are built out of it.
No. 1680 is a composite number — it has 40 factors, and breaks down into 2⁴ × 3 × 5 × 7.
The lowest common multiple of 1680 and 2 is 1,680. It is the first number that appears in both multiplication tables.
