LCM of two numbers in Python

LCM of two numbers in Python using functions

How to Find Least Common Multiple (LCM) in Python programming language by using the functions?

What is LCM?

LCM stands for Least Common Multiple/ Lowest Common Multiple.
LCM is a theory of arithmetic and number system.

How to demote LCM of two numbers?

The LCM of two numbers X and Y can be denoted by LCM (X,Y).

In this example, LCM is the lowest positive number that is divisible by both “X” and “Y”.

Example of LCM

We have two integers 1 and 2. Let’s find LCM

Multiples of 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ………and many similar.

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16,………and many similar.

Common multiples of 1 and 2 are will be the numbers that are common in both of these.

2, 4, 6,8, 10, ………and many similar.

LCM is the lowest common multiplier so, in this example, we have 2 as an LCM.

Write a Python program to find LCM of two numbers

# Write a Python function to calculate LCM  
def LCM_T4Tutorials(x, y):  
    # Checking for Big number  
    if x > y:  
        Greater_Number = x  
    else:  
        Greater_Number = y  
    while(True):  
        if((Greater_Number % x == 0) and (Greater_Number % y == 0)):  
            lcm = Greater_Number  
            break  
        Greater_Number += 1  
    return lcm    
  
# Getting input from the users  
num1 = int(input("Please! Enter the first number: "))  
num2 = int(input("Please! Enter the second number: "))  
# Displaying the result for the users  
print("The L.C.M. of", num1,"and", num2,"is", LCM_T4Tutorials(num1, num2))

# Write a Python function to calculate LCM

def LCM_T4Tutorials(x, y):

# Checking for Big number

if x > y:

Greater_Number = x

else:

Greater_Number = y

while(True):

if((Greater_Number % x == 0) and (Greater_Number %

y == 0)):

lcm = Greater_Number

break

Greater_Number += 1

return lcm

# Getting input from the users

num1 = int(input("Please! Enter the first number: "))

num2 = int(input("Please! Enter the second number: "))

# Displaying the result for the users

print("The L.C.M. of", num1,"and", num2,"is", LCM_T4Tutorials(num1, num2))

Output

Please! Enter the first number: 4
Please! Enter the second number: 5
The L.C.M. of 4 and 5 is 20
