### What is Niven Number

- A number is said to be Niven number if it is divisible by the sum of its digits.
- In mathematics Niven number is also known as Harshad number.
- Example: 18, 126, 1729, etc.

Sample input: 126

Then sum of its digits= 1 + 2 + 6 = 9 and 126 is divisible by 9

**// PROGRAM TO CHECK NIVEN NUMBER
import java.util.Scanner;
class Niven
{
public static void main(String args[])
{
int num,sum=0,rem,org_num;
Scanner sc=new Scanner(System.in);
System.out.println("Enter any number");
num=sc.nextInt();
org_num=num;
while(num!=0)
{
rem=num%10;
sum=sum+rem;
num=num/10;
}
if(org_num%sum==0)
System.out.println(org_num+" is Niven number");
else
System.out.println(org_num+" is not a Niven number");
}
}
