Factor trees are a way to notate the process of finding the prime factorization of a given number. Since each number has its own unique prime factorization, each has its own single factor tree.
The purpose of a factor tree is to notate the process of finding the prime factorization. If a number is already prime, a factor tree is not necessary.
The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.
