Multiples of 522 are all integers divisible by 522 , i.e. the remainder of the full division by 522 is zero. There are infinite multiples of 522. The smallest multiples of 522 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 522 since 0 × 522 = 0
522 : in fact, 522 is a multiple of itself, since 522 is divisible by 522 (it was 522 / 522 = 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 522, the answer is: No, 522 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 522). 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 22.847 ). 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.
