Euler's Totient function - a question on efficient implementation


To all:

Bill Allobert's post on finding certain values for the eulerphi() function led me to the Wikiepedia article.

Please see https://en.wikipedia.org/wiki/Euler%27s_totient_function

Is there a way to find a very efficient implementation? At the time of this post, I am not familiar with how GP Pari computes this value.
