What is Prime Factors?
Every whole number greater than 1 is either prime or a product of primes, and that factorisation is unique. It underpins simplifying fractions, GCD and LCM.
How it works
We divide the number by the smallest prime that fits, repeatedly, recording each division until only a prime remains, then collect the exponents.
