Rewrite an Integer as a Product

Rewrite an Integer as a Product takes any list of integers and converts each one into a multiplication of its prime factors. Want to turn 84 into 2 × 2 × 3 × 7? Or maybe into 2² × 3 × 7 with clean exponents? This tool does it instantly with formatting options, symbol styles, and real-time updates.

You can paste your numbers in or import a file, tweak your settings, and get output that flashes into view with every change. It all happens entirely in your browser. No data leaves your device and it’s super fast.
