5801is an odd number,as it is not divisible by 2
The factors for 5801 are all the numbers between -5801 and 5801 , which divide 5801 without leaving any remainder. Since 5801 divided by -5801 is an integer, -5801 is a factor of 5801 .
Since 5801 divided by -5801 is a whole number, -5801 is a factor of 5801
Since 5801 divided by -1 is a whole number, -1 is a factor of 5801
Since 5801 divided by 1 is a whole number, 1 is a factor of 5801
Multiples of 5801 are all integers divisible by 5801 , i.e. the remainder of the full division by 5801 is zero. There are infinite multiples of 5801. The smallest multiples of 5801 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 5801 since 0 × 5801 = 0
5801 : in fact, 5801 is a multiple of itself, since 5801 is divisible by 5801 (it was 5801 / 5801 = 1, so the rest of this division is zero)
11602: in fact, 11602 = 5801 × 2
17403: in fact, 17403 = 5801 × 3
23204: in fact, 23204 = 5801 × 4
29005: in fact, 29005 = 5801 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 5801, the answer is: yes, 5801 is a prime number because it only has two different divisors: 1 and itself (5801).
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 5801). 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 76.164 ). 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.
