0 : in fact, 0 is divisible by any integer, so it is also a multiple of 233 since 0 × 233 = 0

233 : in fact, 233 is a multiple of itself, since 233 is divisible by 233 (it was 233 / 233 = 1, so the rest of this division is zero)

466: in fact, 466 = 233 × 2

699: in fact, 699 = 233 × 3

932: in fact, 932 = 233 × 4

1165: in fact, 1165 = 233 × 5

etc.

## Is 233 a prime number?

It is possible to determine using mathematical techniques whether an integer is prime or not.

for 233, the answer is: yes, 233 is a prime number because it only has two different divisors: 1 and itself (233).

## How do you determine if a number is prime?

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 233). 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 15.264 ). 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.
