If the hcf you mentioned is the same as greatest common divisor (I don't what's the difference between them, if there is!!) then you can notice that any factor of q is power of p then p divide the hcf if it isn't equal to 1. Therefore

which implies, for some (property of prime elements) which is impossible. So the hcf is 1.
