## What are the multiples of 1000?

Multiples of 1000 are all integers divisible by 1000 , i.e. the remainder of the full division by 1000 is zero. There are infinite multiples of 1000. The smallest multiples of 1000 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 1000 since 0 × 1000 = 0

1000 : in fact, 1000 is a multiple of itself, since 1000 is divisible by 1000 (it was 1000 / 1000 = 1, so the rest of this division is zero)

2000: in fact, 2000 = 1000 × 2

3000: in fact, 3000 = 1000 × 3

4000: in fact, 4000 = 1000 × 4

5000: in fact, 5000 = 1000 × 5

etc.

## Is 1000 a prime number?

It is possible to determine using mathematical techniques whether an integer is prime or not.

for 1000, the answer is: No, 1000 is not a prime number.

## How do you determine if a number is prime?

To know the primality of an integer, we can use several algorithms. The most naive is to try all divisors below the number you want to know if it is prime (in our case 1000). We can already eliminate even numbers bigger than 2 (then 4 , 6 , 8 ...). Besides, we can stop at the square root of the number in question (here 31.623 ). Historically, the Eratosthenes screen (which dates back to Antiquity) uses this technique relatively effectively.

More modern techniques include the Atkin screen, probabilistic tests, or the cyclotomic test.
