Factor Tree building procedure:
- Divide the given composite number by its smallest prime factor
- If the resulting quotient is a composite number, divide it by its smallest prime factor
- Repeat until resulting quotient is a prime number

Prime Factorization of 1,728: 1728 = 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3
Prime Factorization of 1,728 in Exponential Form: 1728 = 26 x 33
Note: While the Prime Factorization of a Composite Number is unique, corresponding Factor Trees will differ if a different procedure is used
