0 : in fact, 0 is divisible by any integer, so it is also a multiple of 2816 since 0 × 2816 = 0

2816 : in fact, 2816 is a multiple of itself, since 2816 is divisible by 2816 (it was 2816 / 2816 = 1, so the rest of this division is zero)

5632: in fact, 5632 = 2816 × 2

8448: in fact, 8448 = 2816 × 3

11264: in fact, 11264 = 2816 × 4

etc.

It is possible to determine using mathematical techniques whether an integer is prime or not.

for 2816, the answer is:
**No, 2816 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 2816). 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 53.066 ). 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.
