Is 28001 a prime number?
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 28001, the answer is: yes, 28001 is a prime number because it only has two different divisors: 1 and itself (28001).
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 28001). 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 167.335 ). 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.
