Multiples of 417 are all integers divisible by 417 , i.e. the remainder of the full division by 417 is zero. There are infinite multiples of 417. The smallest multiples of 417 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 417 since 0 × 417 = 0
417 : in fact, 417 is a multiple of itself, since 417 is divisible by 417 (it was 417 / 417 = 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 417, the answer is: No, 417 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 417). 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 20.421 ). 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.
