comment How to transform the output of FactorInteger to a traditional format?
Much better already but I don't want the ^ symbol in 2^3, I want the 3 lifted to the exponent place $2^3$ ( should have used Latex in question I suppose ). I tried adding //TraditionalForm but that did not work.

@ciao - The thing is that the answer in the related question comes awfully close! And that is only a Mma one-liner. - I will get back on this, later.
