Multiples of 7840 are all integers divisible by 7840 , i.e. the remainder of the full division by 7840 is zero. There are infinite multiples of 7840. The smallest multiples of 7840 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 7840 since 0 × 7840 = 0

7840 : in fact, 7840 is a multiple of itself, since 7840 is divisible by 7840 (it was 7840 / 7840 = 1, so the rest of this division is zero)

15680: in fact, 15680 = 7840 × 2

23520: in fact, 23520 = 7840 × 3

31360: in fact, 31360 = 7840 × 4

etc.

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

for 7840, the answer is:
**No, 7840 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 7840). 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 88.544 ). 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.
