0 : in fact, 0 is divisible by any integer, so it is also a multiple of 8220 since 0 × 8220 = 0
8220 : in fact, 8220 is a multiple of itself, since 8220 is divisible by 8220 (it was 8220 / 8220 = 1, so the rest of this division is zero)
16440: in fact, 16440 = 8220 × 2
24660: in fact, 24660 = 8220 × 3

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 8220, the answer is: No, 8220 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 8220). 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 90.664 ). 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.
