What is Prime Factors?
Prime factorization expresses any integer as a product of prime numbers (e.g., 360 = 2³ × 3² × 5). It underlies many areas of mathematics and computer science including cryptography (RSA encryption relies on the difficulty of factoring large numbers), greatest common divisors, and fraction simplification. DailyDevTools' Prime Factorization tool instantly factors any integer and shows the result in both exponential and expanded form.

Frequently asked questions
What is a prime number?
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The first primes are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29. By the Fundamental Theorem of Arithmetic, every integer greater than 1 has a unique prime factorization.
Why is prime factorization important in cryptography?
RSA encryption relies on the fact that multiplying two large primes is fast, but factoring the product back into its primes is computationally infeasible for large numbers. A 2048-bit RSA key uses primes with 300+ digits.
How do I find the GCD using prime factorization?
The GCD is the product of all prime factors common to both numbers, each taken with the smallest exponent. For example, GCD(12, 18) — factors are 2² × 3 and 2 × 3² — GCD = 2¹ × 3¹ = 6.
