Prime Factorization
Decompose numbers into their prime factors.
About Prime Factorization
Prime Factorization decomposes any positive integer into its unique set of prime factor components, expressing the result in exponential notation such as 360 = 2^3 x 3^2 x 5. Prime factorization is a foundational operation in number theory, cryptography, and arithmetic simplification, and underpins algorithms for computing GCD, LCM, and modular inverses. The tool handles integers of practical size instantly and displays factors in ascending order with their exponents clearly labeled. Understanding the prime decomposition of a number is also essential for simplifying fractions and analyzing divisibility.
How to Use
Enter any positive integer in the input field and click Factorize to see the complete prime factorization displayed in exponential notation. The tool also lists each distinct prime factor individually so you can quickly count the number of prime factors and their multiplicities. For composite numbers, the factorization tree is shown to help visualize how the number breaks down step by step. Copy the output for use in mathematical proofs, homework solutions, or educational material.
