How to Use the Prime Factor Calculator

Introduction

The Prime Factor Calculator is a useful tool that allows you to factorize an integer into its prime components. This guide will take you through each step required to use the calculator effectively.

Step-by-Step Guide

Step 1: Locate the Input Field

Find the input field labeled Enter a Positive Integer. This is where you will enter the number you wish to factorize. Ensure the number is a positive integer as specified by the placeholder text: Enter a number to factorize.

Step 2: Enter the Number

  • In the numberInput field, enter a positive integer that you want to factorize.
  • Remember to adhere to the validation rules: the number must be between 1 and 999,999,999 and should be in whole numbers (no fractions or decimals).

Step 3: View the Prime Factors

  • Once you have entered your number, the calculator will perform the calculation logic: getPrimeFactors(numberInput).
  • The result will appear under the label Prime Factors, formatted as a list with square brackets, e.g., [2, 3, 5].

Step 4: Determine the Number of Prime Factors

  • Additionally, the calculator provides the Number of Prime Factors by executing the logic: countPrimeFactors(numberInput).
  • This result is displayed as a single integer showing the total number of prime factors.

Step 5: Identify the Largest Prime Factor

  • The calculator identifies and displays the Largest Prime Factor by using the logic: max(getPrimeFactors(numberInput)).
  • This value is presented as a single integer.

Step 6: View the Prime Factorization Expression

  • The calculator creates a Prime Factorization Expression using the logic: formatPrimeFactorization(numberInput).
  • This expression displays how the original number can be expressed as a product of prime factors.

Step 7: Check If the Number is Prime

  • Finally, the calculator assesses if your number is a prime number by applying the logic: isPrime(numberInput).
  • The result is displayed as 1 (Yes, the number is prime) or 0 (No, the number is not prime) for the label Is Prime Number.

By following these steps, you can efficiently use the Prime Factor Calculator to find prime factors and related information about any given positive integer.
