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

11 is a prime number. Prime numbers don't have trees. Their only prime factor is themselves.

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.
3x7=21 3 and 7 are prime numbers, so 3x7 is the factor tree of the number 21.
You don't. 41 is a prime number. Prime numbers don't have factor trees, since they only have one prime factor.
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.
