0 : in fact, 0 is divisible by any integer, so it is also a multiple of 82 since 0 × 82 = 0

82 : in fact, 82 is a multiple of itself, since 82 is divisible by 82 (it was 82 / 82 = 1, so the rest of this division is zero)

164: in fact, 164 = 82 × 2

246: in fact, 246 = 82 × 3

328: in fact, 328 = 82 × 4

410: in fact, 410 = 82 × 5

etc.

## Is 82 a prime number?

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

for 82, the answer is: No, 82 is not a prime number.

## How do you determine if a number is prime?

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 82). 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 9.055 ). 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.
