Suppose you have a number N and you want to find its largest prime factor. It is probably easiest to start at the bottom.Find the smallest prime factor, p.Find its factor pair = N/p.If the second number (= N/p) is a prime, then it is the largest prime factor.if not, replace N by N/p and go back to the top.
A factor tree is a representation of the process of finding the prime factorization of a given number.

Whatever you use, 59 is a prime number. Its only prime factor is itself.
If the prime factorization contains a 5 and a 7, 35 is a factor.

You cannot "solve" a single number!
Instead of saying, "Please write that number as a product of its prime factors," people might say, "Please factor that number."
Since 81 is a composite number, you use composite factorization. 81x2x2x2x2 is 1,296.
No because you have to have a prime number besides 1 like 2,5,7 because every time you use a factor tree and you put a 1 as prime you keep getting one every time.So one can not be use as a factor when doing a factor tree.
