0 : in fact, 0 is divisible by any integer, so it is also a multiple of 1308 since 0 × 1308 = 0
1308 : in fact, 1308 is a multiple of itself, since 1308 is divisible by 1308 (it was 1308 / 1308 = 1, so the rest of this division is zero)
2616: in fact, 2616 = 1308 × 2
3924: in fact, 3924 = 1308 × 3
5232: in fact, 5232 = 1308 × 4

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 1308, the answer is: No, 1308 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 1308). 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 36.166 ). 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.
