Multiples of 2223 are all integers divisible by 2223 , i.e. the remainder of the full division by 2223 is zero. There are infinite multiples of 2223. The smallest multiples of 2223 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 2223 since 0 × 2223 = 0
2223 : in fact, 2223 is a multiple of itself, since 2223 is divisible by 2223 (it was 2223 / 2223 = 1, so the rest of this division is zero)
4446: in fact, 4446 = 2223 × 2
6669: in fact, 6669 = 2223 × 3
8892: in fact, 8892 = 2223 × 4
11115: in fact, 11115 = 2223 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 2223, the answer is: No, 2223 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 2223). 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 47.149 ). 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.
