# Java Program to check Krishnamurthy Number3 min read

In this tutorial, we will learn about Krishnamurthy numbers and write a Krishnamurthy Number program in Java. We will write two programs for Krishnamurthy number in java.

## Krishnamurthy Number

A number is said to be a Krishnamurthy Number if the sum of the factorial of all digits of a number is equal to the original number itself. Krishnamurthy Number is also known as Strong number and is frequently asked questions in interviews.

Example:

Input: 145
Output: Krishnamurthy Number
= 1! + 4! + 5!
= 1 + 24 + 120
= 145
= Original Number

## Java Program to check Krishnamurthy Number

Output:

`//Run: 1 Enter an integer: 145 145 is a Krishnamurthy number `

`//Run: 2 Enter an integer: 123 123 is not a Krishnamurthy number`

We have created two different user-defined functions, one to calculate the factorial of a number and another to check the number for Krishnamurthy which is a boolean function.

### Java Program to check Krishnamurthy number within the given Range

Output:

As you can see, we did the same way by creating separate functions but here we took the user input for both the lower and upper range and called the function within those ranges to find all the possible Krishnamurthy number java.
