Ofte stilte spørsmål
- What is prime factorisation?
- Writing a number as a product of primes, e.g. 360 = 2³ × 3² × 5. Every whole number above 1 has a unique prime factorisation.
- How large a number can it factor?
- Up to one billion. It divides out prime factors by trial division up to the square root, which stays fast within that range.
- What else does it show?
- The full factorisation expression, each prime's exponent, and the complete list of divisors of the number.
- Is my number uploaded?
- No. The factorisation is done in your browser; the number you enter never leaves the page.
