Check if the sum of digits of a number N divides it

Last Updated : 30 Apr, 2021

Given a number N. The task is to check if the sum of digits of the given number divides the number or not. If it divides it then print YES otherwise print NO.
Examples:

Input : N = 12
Output : YES
Sum of digits = 1+2 =3 and 3 divides 12.
So, print YES.

Input : N = 15
Output : NO

Extract digits of the number and calculate the sum of all of its digits and check if the sum of digits dives N or not.
Below is the implementation of the above approach:

C++

// C++ program to check if sum of
// digits of a number divides it
 
#include <iostream>
using namespace std;
 
// Function to check if sum of
// digits of a number divides it
int isSumDivides(int N)
{
    int temp = N;
 
    int sum = 0;
 
    // Calculate sum of all of digits of N
    while (temp) {
        sum += temp % 10;
        temp /= 10;
    }
 
    if (N % sum == 0)
        return 1;
    else
        return 0;
}
 
// Driver Code
int main()
{
    int N = 12;
 
    if (isSumDivides(N))
        cout << "YES";
    else
        cout << "NO";
 
    return 0;
}

Java

// Java program to check if sum of
// digits of a number divides it
 
import java.util.*;
import java.lang.*;
 
class GFG
{
// Function to check if sum of
// digits of a number divides it
static int isSumDivides(int N)
{
    int temp = N;
 
    int sum = 0;
 
    // Calculate sum of all of digits of N
    while (temp > 0)
    {
        sum += temp % 10;
        temp /= 10;
    }
 
    if (N % sum == 0)
        return 1;
    else
        return 0;
}
 
// Driver Code
public static void main(String args[])
{
    int N = 12;
 
    if (isSumDivides(N) == 1)
        System.out.print("YES");
    else
        System.out.print("NO");
}
}

    while (temp):
        sum += temp % 10
        temp = int(temp / 10)
