Multiples of 564 are all integers divisible by 564 , i.e. the remainder of the full division by 564 is zero. There are infinite multiples of 564. The smallest multiples of 564 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 564 since 0 × 564 = 0
564 : in fact, 564 is a multiple of itself, since 564 is divisible by 564 (it was 564 / 564 = 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 564, the answer is: No, 564 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 564). 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 23.749 ). 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.
