Number Theory
Factorial Calculator
Compute the factorial n!, the product of all positive integers up to n. It is essential for permutations, combinations, and probability calculations.
Fill in the required fields to see your result.
Math
Prime Factorization Calculator
Decompose any positive integer into its unique product of prime numbers — the fundamental "atomic" representation that underlies divisibility, fractions, modular arithmetic, and cryptography. The result is returned as a space-separated multiplication expression.
