Program to Display Factors of a Number - (C# Basic Programs)

Finding the factors of a given number is a common programming exercise that is helpful in many applications, such as calculating prime numbers and solving mathematical problems. In this tutorial, we will discuss a program in C# programming language to display the factors of a number.

Syntax

The syntax for finding the factors of a number in C# is as follows:

for (int i = 1; i <= number; i++) {
  if (number % i == 0) {
    Console.Write(i + " ");
  }
}

Example

using System;

namespace FactorOfNumber
{
    class Program
    {
        static void Main(string[] args)
        {
            int number;
            Console.Write("Enter a positive integer: ");
            number = int.Parse(Console.ReadLine());

            Console.Write("Factors of " + number + " are: ");
            for (int i = 1; i <= number; i++)
            {
                if (number % i == 0)
                {
                    Console.Write(i + " ");
                }
            }

            Console.ReadKey();
        }
    }
}

Output:

Enter a positive integer: 24
Factors of 24 are: 1 2 3 4 6 8 12 24

Explanation

In this program, we first prompt the user to input a positive integer. We then use a for loop to iterate over all possible factors of the given number. If the current index i is a factor of the number (determined by checking if the remainder after dividing number by i is zero), we print it to the console.

Use

The program to display factors of a number is useful in many real-world applications, such as calculating prime numbers, finding factors of large numbers in cryptography, and solving mathematical problems.

Summary

In this tutorial, we have discussed a program in C# programming language to display the factors of a given number. We have seen the syntax, example, explanation, and use of a program to display factors of a number. By practicing these exercises, programmers can improve their problem-solving skills and become better equipped to tackle complex coding challenges.
