Factor trees lead to prime factorizations. Negative numbers don't have prime factorizations. We'll do 98. If you want, you can put -1 in front of it. 98 49,2 7,7,2
To simplify fractions, it is necessary to divide the numerator and the denominator by their GCF. You can find their GCF by comparing their prime factorizations. You can find their prime factorizations through the use of factor trees.
The factor tree finds the prime factorization of a given number. Combining the prime factorizations of two denominators correctly will give you their least common denominator.
Denominators are just numbers. Factoring them into primes meanss finding their prime factorizations. A factor tree can help you visualize this.
In all but the topmost branch, they're mandatory. it doesn't make sense to put a prime number at the top of a tree, since prime numbers don't have prime factorizations. The only prime factor of a prime number is the number itself, so the tree doesn't have anywhere to go.
29 is already prime. No tree. 87 3,29 Since there are no common prime factors, the GCF is 1.
We generally don't do factor trees of negative numbers, since factor trees are designed to obtain the prime factorization and negative numbers don't have prime factorizations. Here's 400: 400 200,2 100,2,2 50,2,2,2 25,2,2,2,2 5,5,2,2,2,2
A factor tree of number is (I think) the numbers that multiply together to form a product. They are prime numbers, too.
83 is prime. No tree.

IT IS PRIME there is no factor tree
If you're asking about prime factorizations, the process is the same, no matter the size of the number. Use a factor tree. Larger numbers are likely to have more branches.
