Really great!! I really appreciate the way you explain. Very simple with no complicated words and theoretical messes.

Salam Mr.Noureddin Sadawi

You learned me in data mining cource and now you teach me in my security cource

May Allah help you and guide you to jannah

Thanks alot, , All my peace and blessings🙏🏻

Very well done, thank you for taking the time to make this video

No, it's actually `≤ n`. Sure, most numbers cannot be relatively prime to itself, so it would be unnecessary to test `n`. BUT! it is useful to include `n`, because if `n` is 1, then `GCD(1, 1) = 1`, and `1` is counted, so you don't have to account for it by making a special case that `φ(1) = 1`, it works out of the box ;)

You said in the title that how it works but u failed to prove the properties
