840
That is 1 multiples of 840 below 1,000, ending at 840.
Factors are the mirror image of multiples: they divide into 840 exactly, rather than being built from it. The factors of 840 are 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840.
Written as pairs: 1 × 840, 2 × 420, 3 × 280, 4 × 210, 5 × 168, 6 × 140, 7 × 120, 8 × 105, 10 × 84, 12 × 70, 14 × 60, 15 × 56, 20 × 42, 21 × 40, 24 × 35, 28 × 30.
Broken all the way down into primes, 840 = 2³ × 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 840 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 840 and 2 | 840 | 2 | 1,680 |
| 840 and 3 | 840 | 3 | 1,680 |
| 840 and 4 | 840 | 4 | 1,680 |
| 840 and 5 | 840 | 5 | 1,680 |
| 840 and 6 | 840 | 6 | 1,680 |
Start at 840 and keep adding 840. That gives 840, 1680, 2520, 3360, 4200, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 840 × 7 = 5,880 saves you counting seven hops one at a time.
Because 840 is even, every one of its multiples is even too — you will never find an odd number in this table.
Multiples of 840 always end in 0 or 5, which is why they turn up so often in money and measurement problems.
The multiples of 840 are 840, 1680, 2520, 3360, 4200, 5040, 5880, 6720, 7560, 8400, and so on. Each one is 840 multiplied by a whole number, so the list continues without end.
840 is larger than 100, so it has no multiples in that range.
There are 1 multiples of 840 below 1,000. They run from 840 up to 840.
The 10th multiple of 840 is 840 × 10 = 8,400.
The factors of 840 are 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840 — 32 in total. Factors divide into 840; multiples are built out of it.
No. 840 is a composite number — it has 32 factors, and breaks down into 2³ × 3 × 5 × 7.
