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.

What is prime factor tree for 13?
'13' is a prime number, so there is no factor tree. However, to test , we can say 13)13 = 1 When reduced to '1' the factoring is complete. Prime numbers are 2,3,5,7,11,13,17,19,23,29.... This goes to infinity, however, the above list is primes to '30'.

Why do factor trees always come up with the GCF?
Factor trees come up with prime factorizations. When you compare one prime factorization with another, you can come up with a GCF.
How do you make a factor tree of 41 with the final answer a exponet?
You don't. 41 is a prime number. Prime numbers don't have factor trees, since they only have one prime factor.
