13033is an odd number,as it is not divisible by 2
The factors for 13033 are all the numbers between -13033 and 13033 , which divide 13033 without leaving any remainder. Since 13033 divided by -13033 is an integer, -13033 is a factor of 13033 .
Since 13033 divided by -13033 is a whole number, -13033 is a factor of 13033
Since 13033 divided by -1 is a whole number, -1 is a factor of 13033
Since 13033 divided by 1 is a whole number, 1 is a factor of 13033
Multiples of 13033 are all integers divisible by 13033 , i.e. the remainder of the full division by 13033 is zero. There are infinite multiples of 13033. The smallest multiples of 13033 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 13033 since 0 × 13033 = 0
13033 : in fact, 13033 is a multiple of itself, since 13033 is divisible by 13033 (it was 13033 / 13033 = 1, so the rest of this division is zero)
26066: in fact, 26066 = 13033 × 2
39099: in fact, 39099 = 13033 × 3

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 13033, the answer is: yes, 13033 is a prime number because it only has two different divisors: 1 and itself (13033).
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 13033). 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 114.162 ). 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.
