Enter a whole number and get its complete prime factorization in two clear formats: the full expanded product and the tidy exponent form. Prime factorization breaks a number down into the prime building blocks that multiply together to make it, which is the foundation for finding greatest common divisors, least common multiples, and for simplifying fractions and radicals. This tool divides out each prime in order, so it stays fast even for larger numbers, and it always returns the exact factors. It is useful for algebra homework, number theory, and quick sanity checks. Just type your number and read off the factors. All of the work happens locally in your browser, so nothing you enter ever leaves your device.
