Multiples of 906 are all integers divisible by 906 , i.e. the remainder of the full division by 906 is zero. There are infinite multiples of 906. The smallest multiples of 906 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 906 since 0 × 906 = 0

906 : in fact, 906 is a multiple of itself, since 906 is divisible by 906 (it was 906 / 906 = 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 906, the answer is:
**No, 906 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 906). 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 30.1 ). 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.
