0 : in fact, 0 is divisible by any integer, so it is also a multiple of 1920 since 0 × 1920 = 0
1920 : in fact, 1920 is a multiple of itself, since 1920 is divisible by 1920 (it was 1920 / 1920 = 1, so the rest of this division is zero)
3840: in fact, 3840 = 1920 × 2
5760: in fact, 5760 = 1920 × 3
7680: in fact, 7680 = 1920 × 4

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 1920, the answer is: No, 1920 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 1920). 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 43.818 ). 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.
