Then, follow the prime factorization steps outlined in the previous section. The procedure is the same, except you write each of the factor pairs underneath the previous numbers.

These prime power towers represent the leaf node paths of a tree. The method relies on recursively factoring a number N until all exponents are prime and mapping the branching structure that results ...

Using prime factors to find the HCF and LCM Numbers can be broken down into prime factors using prime factor trees.

Learn how to work out the factors of a number using a diagrammatic representation and factor trees in this KS3 maths study guide from BBC Bitesize.
