Multiples of 8640 are all integers divisible by 8640 , i.e. the remainder of the full division by 8640 is zero. There are infinite multiples of 8640. The smallest multiples of 8640 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 8640 since 0 × 8640 = 0

8640 : in fact, 8640 is a multiple of itself, since 8640 is divisible by 8640 (it was 8640 / 8640 = 1, so the rest of this division is zero)

17280: in fact, 17280 = 8640 × 2

25920: in fact, 25920 = 8640 × 3

34560: in fact, 34560 = 8640 × 4

43200: in fact, 43200 = 8640 × 5

etc.

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

for 8640, the answer is:
**No, 8640 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 8640). 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 92.952 ). 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.
