About this calculator
Prime Factorization Calculator is a professional number theory tool for factoring positive integers into products of prime factors. Prime factorization is the basis of number theory. According to the fundamental theorem of arithmetic, every positive integer greater than 1 can be uniquely expressed as a product of prime numbers. For example, 60=2²×3×5. Prime factor decomposition has important applications in cryptography, number theory research, algorithm analysis and other fields. This calculator uses efficient algorithms and supports the decomposition of large numbers. It can quickly find all prime factors and their exponents, and provides a detailed decomposition process.
