Prime Factorization Calculator

Last Updated : 9 Mar, 2026

Prime factorization is the process of breaking down a positive integer into its prime factors.

Steps to Use the Prime Factorization Calculator

To use the provided prime factorization calculator, you can follow the following steps:

Step 1: Enter the number for which you want to find prime factors or all factors, or perform prime factorization.

Step 2: Click 'Factorize'

Step 3: You will receive the results, including prime factors, prime factorization, and all possible factors of the input number.

Step 4: Enter another number to find its prime factors.

How does the Prime Factorization Calculator work

Let's understand the working of this Prime Factorization Calculator using the following example:

For example, let's consider the prime factorization of 36.

  • Start with 36.
  • Divide by 2: 36 ÷ 2 = 18. Record 2.
  • Divide by 2 again: 18 ÷ 2 = 9. Record 2 2 .
  • Divide by 3: 9 ÷ 3 = 3. Record 3.
  • Divide by 3 again: 3 ÷ 3 = 1. Record 3 2 .

So, the prime factorization of 36 is 22 × 32, which means that 36 can be expressed as the product of two 2s and two 3s.
