0 : in fact, 0 is divisible by any integer, so it is also a multiple of 20800 since 0 × 20800 = 0
20800 : in fact, 20800 is a multiple of itself, since 20800 is divisible by 20800 (it was 20800 / 20800 = 1, so the rest of this division is zero)
41600: in fact, 41600 = 20800 × 2
62400: in fact, 62400 = 20800 × 3

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 20800, the answer is: No, 20800 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 20800). 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 144.222 ). 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.
