# Print LCM of Two Integers in Java

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 Java.

## 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.

## Java Program To Print LCM of Two Integers

**Input:**

**a = 15, b = 20**

**Output:**

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

// Java program to find LCM of two numbers. class TechDecodeTutorials { // Recursive method to return gcd of a and b static int gcd(int a, int b) { if (a == 0) return b; return gcd(b % a, a); } // method to return LCM of two numbers static int lcm(int a, int b) { return (a / gcd(a, b)) * b; } // Driver method public static void main(String[] args) { int a = 15, b = 20; System.out.println("LCM of " + a + " and " + b + " is " + lcm(a, b)); } }
