2309is an odd number,as it is not divisible by 2
The factors for 2309 are all the numbers between -2309 and 2309 , which divide 2309 without leaving any remainder. Since 2309 divided by -2309 is an integer, -2309 is a factor of 2309 .
Since 2309 divided by -2309 is a whole number, -2309 is a factor of 2309
Since 2309 divided by -1 is a whole number, -1 is a factor of 2309
Since 2309 divided by 1 is a whole number, 1 is a factor of 2309
Multiples of 2309 are all integers divisible by 2309 , i.e. the remainder of the full division by 2309 is zero. There are infinite multiples of 2309. The smallest multiples of 2309 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 2309 since 0 × 2309 = 0
2309 : in fact, 2309 is a multiple of itself, since 2309 is divisible by 2309 (it was 2309 / 2309 = 1, so the rest of this division is zero)
4618: in fact, 4618 = 2309 × 2
6927: in fact, 6927 = 2309 × 3
9236: in fact, 9236 = 2309 × 4
11545: in fact, 11545 = 2309 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 2309, the answer is: yes, 2309 is a prime number because it only has two different divisors: 1 and itself (2309).
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 2309). 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 48.052 ). 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.
