0 : in fact, 0 is divisible by any integer, so it is also a multiple of 6400 since 0 × 6400 = 0
6400 : in fact, 6400 is a multiple of itself, since 6400 is divisible by 6400 (it was 6400 / 6400 = 1, so the rest of this division is zero)
12800: in fact, 12800 = 6400 × 2
19200: in fact, 19200 = 6400 × 3

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 6400, the answer is: No, 6400 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 6400). 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 80 ). 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.
