The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.
19 is already prime; no need for a tree.
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.
When the bottom branch consists entirely of prime numbers.
69 3,23
1,2,3,4,6,8,12,24,53,106,159,212,318,424,636,1272
Prime numbers don't have factor trees. So if you can create a tree, your number's composite.

No.
No.
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.

There is no factor tree nor factors of 57 as it is a prime number.
13 is a prime number so it doesn't have a factor tree.
19 is prime. No tree.
no
A factor tree of number is (I think) the numbers that multiply together to form a product. They are prime numbers, too.
