# Print LCM of Two Integers in Python

Computations and programming when combined make a very deadly combination. As the ability to solve complex mathematical questions in itself is a great deal. But when one has to do the same thing by writing up a code, things get somewhat more complicated. Not to mention the language your coding in also determines whether it’s going to be easy to difficult. So today we’re going to write a program to print **LCM** of Two Integers in Python.

## What’s The Approach?

- Let us consider a and b to be the two Integers to find LCM of.

- Firstly we’ll
**find the gcd of these two numbers**, i.e, using a condition where if**a****becomes zero we’ll return**else we’ll recursively`b`

`return`

**b % a, a**

- Next, we’ll
**return multiplication**of**a with gcd**of two numbers, and**again multiply it with b**. The returned value will be our LCM.

## Python Program To Print LCM of Two Integers

**Input:**

**a = 15, b = 20**

**Output:**

**LCM of 1****5 and 20 is 60**

# Python program to find LCM of two numbers # Recursive function to return gcd of a and b def gcd(a,b): if a == 0: return b return gcd(b % a, a) # Function to return LCM of two numbers def lcm(a,b): return (a / gcd(a,b))* b # Driver program to test above function a = 15 b = 20 print('LCM of', a, 'and', b, 'is', lcm(a, b))
