Why? I don't know the exact reason.
Apparently because 1 is a unit and not a number.
Or because a prime number needs to have exactly 2 divisors (itself and 1) which is not the case for 1.

Wait... Oh no it's a bait.
I can see the people who spend their entire day reading the dictionary and Wikipedia are out in full force again today. This bug is never going to be fixed because people are even debating something obvious like 1 being indivisible.

Reading the dictionary and Wikipedia has not taught you any common sense. Go find a number other than 1 that divides 1.
