A factor tree of number is (I think) the numbers that multiply together to form a product. They are prime numbers, too.

630 315,2 105,3,2 35,3,3,2 7,5,3,3,2

16 8,2 4,2,2 2,2,2,2

59 is a prime number and as such has only two factors: 1 and 59 A factor tree doesn't make sense for prime numbers since it would only have one branch: the number 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.

3x7=21 3 and 7 are prime numbers, so 3x7 is the factor tree of the number 21.

You cannot really make a factor tree for 7 because it is already a prime number.

You don't. 41 is a prime number. Prime numbers don't have factor trees, since they only have one prime factor.

A factor tree is when you take a number and bring it down to prime numbers. You do this by diving the number, and drawing to lines from the number and putting the two numbers that multiply into the starting number. You do that until you have all prime numbers. This skill can be usefull for greatest common factor and lowest commen multiple.

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.

A factor tree is a way to notate the process of finding the prime factorization of a given number. A factor tree is complete when the bottom branch (row) consists entirely of prime numbers.
