400 is larger than 100, so it has no multiples below 100. Its first multiple is 400 itself.
400, 800
That is 2 multiples of 400 below 1,000, ending at 800.
Factors are the mirror image of multiples: they divide into 400 exactly, rather than being built from it. The factors of 400 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400.
Written as pairs: 1 × 400, 2 × 200, 4 × 100, 5 × 80, 8 × 50, 10 × 40, 16 × 25, 20 × 20.
Broken all the way down into primes, 400 = 2⁴ × 5².
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 400 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 400 and 2 | 400 | 2 | 800 |
| 400 and 3 | 1,200 | 1 | 2,400 |
| 400 and 4 | 400 | 4 | 800 |
| 400 and 5 | 400 | 5 | 800 |
| 400 and 6 | 1,200 | 2 | 2,400 |
Start at 400 and keep adding 400. That gives 400, 800, 1200, 1600, 2000, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 400 × 7 = 2,800 saves you counting seven hops one at a time.
Because 400 is even, every one of its multiples is even too — you will never find an odd number in this table.
Multiples of 400 always end in 0 or 5, which is why they turn up so often in money and measurement problems.
The multiples of 400 are 400, 800, 1200, 1600, 2000, 2400, 2800, 3200, 3600, 4000, and so on. Each one is 400 multiplied by a whole number, so the list continues without end.
400 is larger than 100, so it has no multiples in that range.
There are 2 multiples of 400 below 1,000. They run from 400 up to 800.
The 10th multiple of 400 is 400 × 10 = 4,000.
The factors of 400 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400 — 15 in total. Factors divide into 400; multiples are built out of it.
No. 400 is a composite number — it has 15 factors, and breaks down into 2⁴ × 5².
The lowest common multiple of 400 and 2 is 400. It is the first number that appears in both multiplication tables.
