Enter a number to find its prime factors and view the step-by-step process.

What is Prime Factorization?

Prime factorization is the process of breaking down a number into its prime number components. A prime number is any number greater than 1 that can only be divided by 1 and itself. For example:

  • The number 28 can be expressed as ( 2 \times 2 \times 7 ), where ( 2 ) and ( 7 ) are prime numbers.
  • The number 17 is a prime number because it cannot be factored further.

Prime factorization is a fundamental concept in mathematics used for simplifying fractions, finding least common multiples (LCMs), and greatest common divisors (GCDs).

Example Calculations

Example 1: Prime Number

Input: 17

Output: - 17 is a prime number. A prime number is a number greater than 1 that can only be divided by 1 and itself. - Step-by-Step: No further factorization needed as 17 is already prime.

Example 2: Composite Number

Input: 95

Output: - Prime Factors: 5 × 19 - Step-by-Step Process: 1. Divide 95 by 5. Result: 19 2. Divide 19 by 19. Result: 1

FAQ

1. What is a prime number?

A prime number is any number greater than 1 that cannot be divided evenly by any number other than 1 and itself. Examples include 2, 3, 5, 7, 11, and 13.

2. What is prime factorization used for?

Prime factorization is used in many areas of mathematics, including: - Simplifying fractions. - Finding least common multiples (LCM) and greatest common divisors (GCD). - Cryptography and computer science.

3. What happens if I enter a number less than 2?

The calculator will alert you to enter a number greater than or equal to 2. Prime factorization is only valid for integers starting from 2.

4. Can I use the calculator for very large numbers?

Yes, the calculator can handle large numbers, though the computation time may increase with extremely large inputs.

5. Why does the calculator explain prime numbers?

Understanding prime numbers is key to understanding factorization. The calculator educates users by identifying primes and explaining their importance.
