**What is Harshad Number**

According to Wikipedia,In mathematics, a Harshad number or Niven number is an integer (in base 10 or any given number base) that is divisible by the sum of its digits when written in that base.

**Examples:**

Number to check: 200

`Sum of digits: 2+0+0 = 2 `

Is 200(Given number) divisible by 2(Sum of digits): Yes //200 is a Harshad number

` `

Number to check: 60

`Sum of digits: 6+0 = 6 `

Is 60(Given number) divisible by 6(Sum of digits): Yes //60 is a Harshad number

Below are examples of numbers which are NOT Harshad numbers:

Number to check: 205

`Sum of digits: 2+0+5 = 7 `

Is 205(Given number) divisible by 7(Sum of digits): No //205 is NOT a Harshad number

` `

Number to check: 85

`Sum of digits: 8+5 = 13 `

Is 85(Given number) divisible by 13(Sum of digits): No //85 is NOT a Harshad number

**List of Harshad numbers from 1 to 50 are:**1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 18, 20, 21, 24, 27, 30, 36, 40, 42, 45, 48, 50

**Java Program for Harshad Number**

import java.util.*; public class JavaHungry { public static void main(String args[]) { System.out.println("Enter any number : "); Scanner scan = new Scanner(System.in); Integer inputNumber = scan.nextInt(); checkHarshadNumber(inputNumber); } public static void checkHarshadNumber(int inputNumber) { int sumOfDigits = 0; int number = inputNumber; while(number > 0) { int remainder = number % 10; sumOfDigits = sumOfDigits + remainder; number = number/10; } if(inputNumber % sumOfDigits == 0) System.out.println(inputNumber +" is a Harshad Number"); else System.out.println(inputNumber + " is NOT a Harshad Number"); } }

**Output:**

**Enter any number :**

11 is NOT a Harshad Number

11 is NOT a Harshad Number

##
**Algorithm For Harshad Number **

1. Calculate the sum of digits of the *inputNumber*.

2. If

*inputNumber*is divisible by

*sumOfDigits*then the

*inputNumber*is Harshad number otherwise not.
