Since prime numbers only have one prime factor (themselves), factor trees are unnecessary.
The bottom branch of a factor tree consists entirely of prime numbers.
When the bottom branch consists entirely of prime numbers.
A factor tree of number is (I think) the numbers that multiply together to form a product. They are prime numbers, too.
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.
Prime numbers don't have trees.
a factor tree
Here is a factor tree of 39: 39 3 x 13 Since these are prime numbers, the factor tree is finished. The prime factors of 39 are 3 and 13.
11 is a prime number. Prime numbers don't have trees. Their only prime factor is themselves.
Prime numbers don't have factor trees. So if you can create a tree, your number's composite.
Use a factor tree. 98 49,2 7,7,2
