Their at the bottom of the tree because the hole point of a factor tree is to find the prime factorization of the number, so it would be at the bottom of the tree.

The bottom branch of a factor tree consists entirely of prime numbers.
Factor trees are ways of notating the process of finding the prime factorization of a given composite number and, as such, should result in an identifiable string of prime factors.
as you can obviously see the bottom of a factor tree would be the curious numbers of 2,2,3,5
A factor tree is a way of notating the process of finding the prime factorization of a given number. As long as the bottom branch consists entirely of prime numbers, it doesn't really matter how they're lined up.
A factor tree of number is (I think) the numbers that multiply together to form a product. They are prime numbers, too.
