1. ש-המספר 1 הוא גם ראשוני.
2. שהמספר 1 אינו ראשוני.
prime number p is a natural number that is divisible by 1 and p.
1 indeed satisfies this definition trivially since it's divisible by 1 and 1.
just plug in p=1.
simple logic really.
you just need to tweak a little bit the fundamental theorem of arithmetics.
