0 : in fact, 0 is divisible by any integer, so it is also a multiple of 1320 since 0 × 1320 = 0
1320 : in fact, 1320 is a multiple of itself, since 1320 is divisible by 1320 (it was 1320 / 1320 = 1, so the rest of this division is zero)
2640: in fact, 2640 = 1320 × 2
3960: in fact, 3960 = 1320 × 3
5280: in fact, 5280 = 1320 × 4

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 1320, the answer is: No, 1320 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 1320). 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 36.332 ). 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.
