109 109 x 1 This is all there is to the factor tree, because 109 is a prime number. Normally, I wouldn't use 1 in a factor tree, but I do in this case to make it clear that I have done a factor tree, since 109 is only divisible by itself and 1.

Every composite number has its own unique tree, so I guess the answer is all numbers have one tree. Perhaps you meant one branch or one factor. Prime numbers only have two factors, one of them is prime, so if you try to do a factor tree with a prime number, it stops the second you write the number down. And then there's one. One only has one factor, so we won't even bother with a tree. We'll call it a factor twig.

Prime numbers don't have factor trees. So if you can create a tree, your number's composite.
Because 45 is not a factor of 60.
A factor tree shows the prime factors of the working number and can also be used as a visual demonstration to show the prime factors of the working number.
199 is a prime number. It does not have a tree since it only has one prime factor, itself.
Only one branch at the bottom of any factor tree.
13 is a prime number. It doesn't have a tree because its only prime factor is itself.
No.
37 is a prime number so it cant be broken into a factor tree. its only factors are 37 and 1
