23041is an odd number,as it is not divisible by 2
The factors for 23041 are all the numbers between -23041 and 23041 , which divide 23041 without leaving any remainder. Since 23041 divided by -23041 is an integer, -23041 is a factor of 23041 .
Since 23041 divided by -23041 is a whole number, -23041 is a factor of 23041
Since 23041 divided by -1 is a whole number, -1 is a factor of 23041
Since 23041 divided by 1 is a whole number, 1 is a factor of 23041
Multiples of 23041 are all integers divisible by 23041 , i.e. the remainder of the full division by 23041 is zero. There are infinite multiples of 23041. The smallest multiples of 23041 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 23041 since 0 × 23041 = 0
23041 : in fact, 23041 is a multiple of itself, since 23041 is divisible by 23041 (it was 23041 / 23041 = 1, so the rest of this division is zero)
46082: in fact, 46082 = 23041 × 2
69123: in fact, 69123 = 23041 × 3
92164: in fact, 92164 = 23041 × 4
115205: in fact, 115205 = 23041 × 5

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 23041, the answer is: yes, 23041 is a prime number because it only has two different divisors: 1 and itself (23041).
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 23041). 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 151.793 ). 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.
