C++ Program to Display Factors of a Number

To understand this example, you should have the knowledge of the following C++ programming topics:

This program takes a positive integer from an user and displays all the factors of that number.

Example: Display all Factors of a Number


              

#include <iostream>
using namespace std;

int main() {
    int n, i;

    cout << "Enter a positive integer: ";
    cin >> n;

    cout << "Factors of " << n << " are: ";
    for(i = 1; i <= n; ++i) {
        if(n % i == 0)
            cout << i << " ";
    }

    return 0;
}

Output


              

Enter a positive integer: 60
Factors of 60 are: 1 2 3 4 5 6 10 12 15 20 30 60

In this program, an integer entered by user is stored in variable n.

Then, for loop is executed with an initial condition i = 1 and checked whether n is perfectly divisible by i or not. If n is perfectly divisible by i then, i will be the factor of n.

In each iteration, the value of i is updated (increased by 1).

This process goes until test condition i <= n becomes false,i.e., this program checks whether number entered by user n is perfectly divisible by all numbers from 1 to n and all displays factors of that number.
