Prime factorization
ClientBreak an integer into its prime factors—helpful for simplifying fractions or verifying divisibility. Pair with GCD & LCM for related number theory tasks.
About Prime factorization
Factor whole numbers into prime products—BigInt trial division in your browser, no upload. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.
How to use this page
Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.

Common mistakes to avoid
Entering 0 or 1
Prime factorization requires an integer greater than 1.
FAQ
How large can the input be?
BigInt arithmetic is used—very large integers work until the browser runs out of memory.
Is data uploaded?
No. Factoring runs entirely in your browser.
