the prime factorization of 32 is 2x2x2x2x2 and the factor tree is 32 8 4 2x4 2x2 2x2
352 prime factorization tree
97 is already prime; no tree required.
23 is a prime number. No prime factorization. No tree.
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
