Or the much simpler counter, anything with a factor of three ain't a 'real' 4096 bit RSA key. Even if it was in use, it would say nothing about RSA. Referring to it as a "4096 bit RSA key" is a red herring.

Also if your modulus ends in A, C, or E you should probably ask for your money back.

It probably also doesn't help that most of the math fails when one of the factors used to generate the key is composite.
