The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.
12q 12,q 6,2,q 3,2,2,q
19 is already prime; no need for a tree.
The greatest common factor of 12 and 20 is 4
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.
12 6,2 3,2,2 There are other possible answers.
12 6,2 3,2,2
12 6,2 3,2,2
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.
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.
