Write a program to calculate GCD and LCM of two number in python code example

Example: python find lcm

def lcm(a, b):
        i = 1
        if a > b:
                c = a
                d = b
        else:
                c = b
                d = a
        while True:
                if ((c * i) / d).is_integer():
                        return c * i
                i += 1;
