# 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` b` else we’ll recursively `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));
}
}
```
