  The fundamental theorem of arithmetic is defined over "every integer greater than 1", not "every whole number" as the post says.

  (and that makes sense intuitively -- what about negative numbers?)

  The idea is cute, but the the wrong theorem definition in the premise really spoils it -- can't recommend this page to anyone.

  Edit: that blog is has wrong math sometimes? Like this page https://alok.github.io/2022/09/22/h455524/ which talks about finite fields and claims "Many results are not true if the underlying field has exactly 2 elements."... but GF(2) exists and is a full-featured field with all theorems being true.
