Multiples of 824 are all integers divisible by 824 , i.e. the remainder of the full division by 824 is zero. There are infinite multiples of 824. The smallest multiples of 824 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 824, the answer is: No, 824 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 824). 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 28.705 ). 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.
