Niven Number – SchoolCodeHub

Niven Number is a number which is divisible by sum of it’s digits.

Example 1: 18. 1+8 = 9. We observe that 18 is divisible by sum of it’s digits 9. Hence it is a Niven Number.

Example 2: 15. 1+5 = 6. Here 15 is not divisible by it’s sum of digits 6. Hence it is not a Niven Number.

Java

import java.util.*;
public class NivenNumber
{
    public static void main(String args[])
    {
        int n=0,r=0,s=0,temp=0;
        Scanner sc=new Scanner(System.in);
        System.out.print("Enter a number: ");
        n=sc.nextInt();
        temp=n;
        while(temp>0)
        {
            r=temp%10;
            s=s+r;
            temp=temp/10;
        }
        if((n%s)==0)
        {
            System.out.println(n+" is a Niven Number");
        }
        else
        {
            System.out.println(n+" is not a Niven Number");
        }
    }
