When do you use a factor tree?
When you want to find the prime factorization of a composite number.
Can 1 and the factor be used itself to be a factor tree?
The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.
What is the factor tree for the number 19?
19 is already prime; no need for a tree.
What is a factor tree and how do youknow when a factor tree is complete?
When the bottom branch consists entirely of prime numbers.
How to get largest prime factor?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210. The largest of those numbers is the largest prime factor.

How can making a factor tree help you find the prime factorization of a number?
If completed correctly, the bottom branch of a factor tree will be the prime factorization of the number at the top.
Why are prime numbers at the bottom of the factor tree?
Their at the bottom of the tree because the hole point of a factor tree is to find the prime factorization of the number, so it would be at the bottom of the tree.
How do you write a factor tree for a prime number?
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.
