Multiples of 2080 are all integers divisible by 2080 , i.e. the remainder of the full division by 2080 is zero. There are infinite multiples of 2080. The smallest multiples of 2080 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 2080 since 0 × 2080 = 0
2080 : in fact, 2080 is a multiple of itself, since 2080 is divisible by 2080 (it was 2080 / 2080 = 1, so the rest of this division is zero)
4160: in fact, 4160 = 2080 × 2
6240: in fact, 6240 = 2080 × 3
8320: in fact, 8320 = 2080 × 4

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 2080, the answer is: No, 2080 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 2080). 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 45.607 ). 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.
