Find Factors of a Number C++ using While loop | For loop

Find factors of a number C++ using while loop and for loop.

In this article, you will learn how to find factors of a number c++ using while loop and for loop.

 

Example-1

 

Example-2

 

What are the factors of a number?

The factors of a number are defined as numbers that divided the original number without leaving any remainder (left reminder = 0).

 

You should have knowledge of the following topics in c++ programming to understand these programs:

• C++ main() function
• C++ for loop statement
• C++ while loop statement
• C++ cin object
• C++ cout object

 

In this article, we solve this problem in two methods:

1. Using the while loop
2. Using the for loop

 

Find Factors of a Number C++ using While loop

// Find Factors of a Number C++ using While loop
#include <iostream>
using namespace std;

int main() {
    int x, i = 1;

    cout << "-----Enter the positive integer number-----\n";
    cin >> x;

    cout << "\nThe factors of the " << x << " are: ";
    while (i <= x) {
        if (x % i == 0) {
            cout << i << " ";
        }
        ++i;
    }
    cout << "\n";
    return 0;
}

Find Factors of a Number C++ using For loop

// Find Factors of a Number C++ using For loop
#include <iostream>
using namespace std;

int main() {
    int x, i;

    cout << "-----Enter the positive integer number-----\n";
    cin >> x;

    cout << "\nThe factors of the " << x << " are: ";
    for (i = 1; i <= x; ++i) {
        if (x % i == 0) {
            cout << i << " ";
        }
    }
    cout << "\n";
    return 0;
}

Explanation

In these given programs, we have taken input 86 a random number then applied the for loop and makes a calculation on this random number.

With Itself reminder zero to find the possible factors of this random number.

The same calculation applied to the second program with while loop.
