Program to find LCM

        if((greater % x == 0) and (greater % y == 0)):  

            lcm = greater  

            break  

        greater += 1  

    return lcm    

num1 = int(input("Enter first number: "))  

num2 = int(input("Enter second number: "))  

print("The L.C.M. of", num1,"and", num2,"is", calculate_lcm(num1, num2))
