0 : in fact, 0 is divisible by any integer, so it is also a multiple of 12301 since 0 × 12301 = 0
12301 : in fact, 12301 is a multiple of itself, since 12301 is divisible by 12301 (it was 12301 / 12301 = 1, so the rest of this division is zero)
24602: in fact, 24602 = 12301 × 2
36903: in fact, 36903 = 12301 × 3
49204: in fact, 49204 = 12301 × 4
61505: in fact, 61505 = 12301 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 12301, the answer is: yes, 12301 is a prime number because it only has two different divisors: 1 and itself (12301).
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 12301). 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 110.91 ). 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.
