0 : in fact, 0 is divisible by any integer, so it is also a multiple of 31800 since 0 × 31800 = 0
31800 : in fact, 31800 is a multiple of itself, since 31800 is divisible by 31800 (it was 31800 / 31800 = 1, so the rest of this division is zero)
63600: in fact, 63600 = 31800 × 2
95400: in fact, 95400 = 31800 × 3

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 31800, the answer is: No, 31800 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 31800). 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 178.326 ). 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.
