Fractions/GCD error with python3.9

[jparsert]

When running irankfinder.py
I get the exception:

....
from fractions import Fraction, gcd
ImportError: cannot import name 'gcd' from 'fractions' (/usr/lib/python3.9/fractions.py)

This might be an exception from https://github.com/jesusjda/pyLPi though.

Thanks for opening the issue.

Your traceback says Python 3.9 and since this version the GCD function has been moved to the math package. I will try to adapt it to this new behaviour.

Changed in version 3.9: The math.gcd() function is now used to normalize the numerator and denominator. math.gcd() always return a int type. Previously, the GCD type depended on numerator and denominator.
