Write the prime factorisation of the number.
Write as a product of primes: 24
Separate the prime factors with a space, comma or × — e.g. 2 2 3.
This exercise breaks a number down into its prime factorisation — the "prime DNA" of the number. Keep dividing the number by the smallest primes (2, 3, 5, 7, …) until you reach 1; list every prime you used as your answer.
What does this generator do?
Picks a composite number between 12 and 100 and asks for its prime factorisation.
How to use it
Keep dividing the number by the smallest primes (2, 3, 5, 7, …) until you reach 1. List every prime you used — order does not matter.
