### 1. Introduction

In this example, we will learn how to get the least common multiple (LCM) of two numbers in Python.

### Source Code

```
#! /usr/bin/env python3
# -*- coding: utf-8 -*-
# Least common multiple
# defined function
def lcm(x, y):
# Get the larger one of x and y as starting number
if x > y:
greater = x
else:
greater = y
while (True):
if ((greater % x == 0) and (greater % y == 0)):
lcm = greater
break
greater += 1
return lcm
num1 = int(input("Enter the first number: "))
num2 = int(input("Enter the second number: "))
print("Least common multiple: ", lcm(num1, num2))
```

```
Enter the first number: 12
Enter the second number: 15
Least common multiple: 60
Enter the first number: 6
Enter the second number: 7
Least common multiple: 42
```
