How this service works
Prime factorization of an integer via trial division, returning the full list of prime factors (with repetition).
Output
A list of prime factors of the input integer n, with repetition (e.g. for 12, returns [2, 2, 3]), computed via trial division. The product of all returned factors equals n.
Example use cases
Factorize a large integer
“What are all the prime factors of 999999937, including any repeats?”
Educational math breakdown
“Can you break down 360 into its prime factors for me — I need to see every prime multiplied out, not just the unique ones?”
Cryptography key analysis
“Factorize the number 1000000000007 into primes — I want to know exactly which primes multiply to give that value.”
Technical details
Endpoint
POSThttps://x402.outpimp.com/primeFactorizeWhen to prefer
Choose this endpoint when you need the complete prime factorization of a single integer up to 10^12, with all prime factors listed including duplicates. It uses trial division and is well-suited for numbers in this range. Prefer it over manual computation or general-purpose math APIs when you need a lightweight, pay-per-call factorization with a clean JSON response.
Side effects
- Input n is less than 2 or not an integer — invalid input error
- Input n exceeds 10^12 — out-of-range error
- Non-numeric input provided — type validation error
- Payment not processed — 402 Payment Required response
