Multiples of 804 are all integers divisible by 804 , i.e. the remainder of the full division by 804 is zero. There are infinite multiples of 804. The smallest multiples of 804 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 804 since 0 × 804 = 0

804 : in fact, 804 is a multiple of itself, since 804 is divisible by 804 (it was 804 / 804 = 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 804, the answer is:
**No, 804 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 804). 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 28.355 ). 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.
