Multiples of 104 are all integers divisible by 104 , i.e. the remainder of the full division by 104 is zero. There are infinite multiples of 104. The smallest multiples of 104 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 104, the answer is: No, 104 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 104). 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 10.198 ). 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.
