To calculate the FACTOR of any integer number

Question - 

Given an integer number, you have to find the all factor of this number.

Example - 

Input : num = 5

Output : 1, 5

Input : num = 12

Output : 1, 2, 3, 4, 6, 12

Approach - 

We divide num with all numbers from 1 to number, if modulus is 0 then it's factor of number.

Implementation -

 

// to find factor of any integer number

#include<iostream>

using namespace std;

int main()

{

    int num;

    cout<<"Enter the number : ";cin>>num;

    cout<<"Factors are : ";

    for(int i=1;i<num;i++){

        if(num%i==0)

        cout<<i<<", ";

    }

    cout<<num;

    return 0;

}
