Multiples of 1863 are all integers divisible by 1863 , i.e. the remainder of the full division by 1863 is zero. There are infinite multiples of 1863. The smallest multiples of 1863 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 1863 since 0 × 1863 = 0

1863 : in fact, 1863 is a multiple of itself, since 1863 is divisible by 1863 (it was 1863 / 1863 = 1, so the rest of this division is zero)

3726: in fact, 3726 = 1863 × 2

5589: in fact, 5589 = 1863 × 3

7452: in fact, 7452 = 1863 × 4

9315: in fact, 9315 = 1863 × 5

etc.

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

for 1863, the answer is:
**No, 1863 is not a prime number**.

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 1863). 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 43.162 ). 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.
