Multiples of 396 are all integers divisible by 396 , i.e. the remainder of the full division by 396 is zero. There are infinite multiples of 396. The smallest multiples of 396 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 396 since 0 × 396 = 0
396 : in fact, 396 is a multiple of itself, since 396 is divisible by 396 (it was 396 / 396 = 1, so the rest of this division is zero)
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 396, the answer is: No, 396 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 396). 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 19.9 ). 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.
