Multiples of 513 are all integers divisible by 513 , i.e. the remainder of the full division by 513 is zero. There are infinite multiples of 513. The smallest multiples of 513 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 513 since 0 × 513 = 0
513 : in fact, 513 is a multiple of itself, since 513 is divisible by 513 (it was 513 / 513 = 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 513, the answer is: No, 513 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 513). 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 22.65 ). 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.
