Multiples of 506 are all integers divisible by 506 , i.e. the remainder of the full division by 506 is zero. There are infinite multiples of 506. The smallest multiples of 506 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 506, the answer is: No, 506 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 506). 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 22.494 ). 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.
