0 : in fact, 0 is divisible by any integer, so it is also a multiple of 9840 since 0 × 9840 = 0

9840 : in fact, 9840 is a multiple of itself, since 9840 is divisible by 9840 (it was 9840 / 9840 = 1, so the rest of this division is zero)

19680: in fact, 19680 = 9840 × 2

29520: in fact, 29520 = 9840 × 3

etc.

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

for 9840, the answer is:
**No, 9840 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 9840). 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 99.197 ). 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.
