How the Prime Factorization / Factor Calculator works.
n = p₁ᵃ¹ × p₂ᵃ² × … × pₖᵃᵏn is a positive integer up to 10¹²; p values are prime factors and a values are their multiplicities.
Worked example for the Prime Factorization / Factor Calculator.
360 becomes 2³ × 3² × 5, and its positive factors are all products formed from those available powers.
How to read this result.
The combined tool can return prime factors, all positive factors, or both for one positive integer.
How the calculation works
Prime factorization divides an integer by each possible prime factor and records the multiplicity; a factor list is built from products of those prime powers. Formula or rule: n = p₁ᵃ¹ × p₂ᵃ² × … × pₖᵃᵏ. n is a positive integer up to 10¹²; p values are prime factors and a values are their multiplicities.
What this calculator does not prove
Trial division is practical within the stated range but is not a cryptographic factorization service and does not factor negative integers, polynomials, or rational expressions. Use the result for the mathematical question shown here; a correct calculation does not by itself establish that the source data, sample, or real-world assumption is appropriate.
Inputs and edge cases to check.
The value must be a positive whole number from 1 through 10¹². One has no prime factors, while a prime is its own prime factor.
What this tool does not include.
Trial division is practical within the stated range but is not a cryptographic factorization service and does not factor negative integers, polynomials, or rational expressions.
