Multiples of 982 are all integers divisible by 982 , i.e. the remainder of the full division by 982 is zero. There are infinite multiples of 982. The smallest multiples of 982 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 982 since 0 × 982 = 0
982 : in fact, 982 is a multiple of itself, since 982 is divisible by 982 (it was 982 / 982 = 1, so the rest of this division is zero)
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 982, the answer is: No, 982 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 982). 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 31.337 ). 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.
