Multiples of 537 are all integers divisible by 537 , i.e. the remainder of the full division by 537 is zero. There are infinite multiples of 537. The smallest multiples of 537 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 537 since 0 × 537 = 0
537 : in fact, 537 is a multiple of itself, since 537 is divisible by 537 (it was 537 / 537 = 1, so the rest of this division is zero)
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 537, the answer is: No, 537 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 537). 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 23.173 ). 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.
