Since 530 divided by -2 is a whole number, -2 is a factor of 530
Since 530 divided by -1 is a whole number, -1 is a factor of 530
Multiples of 530 are all integers divisible by 530 , i.e. the remainder of the full division by 530 is zero. There are infinite multiples of 530. The smallest multiples of 530 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 530, the answer is: No, 530 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 530). 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 23.022 ). 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.
