Prime factorization calculator
Write an integer as a product of prime powers, with an exact-integer factorization path.
How to use this calculator
Replace with an integer. Keep the digits exact rather than entering a rounded decimal approximation.
Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

What to know
Large inputs can exceed the computation time limit. Exact integer handling is not a promise that arbitrary-size factorization will finish.
Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
