Multiples of 682 are all integers divisible by 682 , i.e. the remainder of the full division by 682 is zero. There are infinite multiples of 682. The smallest multiples of 682 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 682 since 0 × 682 = 0
682 : in fact, 682 is a multiple of itself, since 682 is divisible by 682 (it was 682 / 682 = 1, so the rest of this division is zero)
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 682, the answer is: No, 682 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 682). 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 26.115 ). 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.
