No. A Prime number is one that has no factors except the number '1' and itself.
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.
199 is a prime number. It does not have a tree since it only has one prime factor, itself.
19 is prime. No tree.
23 is a prime number. No prime factorization. No tree.
13 is a prime number so it doesn't have a factor tree.
There is no factor tree nor factors of 57 as it is a prime number.
13 is a prime number. It doesn't have a tree because its only prime factor is itself.
The bottom branch of a factor tree consists entirely of prime numbers.
Prime numbers don't have factor trees. So if you can create a tree, your number's composite.
11 is a prime number. Prime numbers don't have trees. Their only prime factor is themselves.
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
