Multiples of 580 are all integers divisible by 580 , i.e. the remainder of the full division by 580 is zero. There are infinite multiples of 580. The smallest multiples of 580 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 580 since 0 × 580 = 0
580 : in fact, 580 is a multiple of itself, since 580 is divisible by 580 (it was 580 / 580 = 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 580, the answer is: No, 580 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 580). 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 24.083 ). 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.
