****The Least Common Multiple****
As a user, I want to use a program which can calculate the least common multiple (L.C.M.) of four numbers.
So that I can find the least common multiple (L.C.M.) of my inputs.
Acceptance Criteria:
Ask user to enter the four numbers.
Use blocks to verify input entries and warn the user for Nan or non numerical inputs.try/except
Calculate the least common multiple (L.C.M.) of four numbers
Use gcd function in module of math
