In this video we learn how to find the prime factorization of a composite number using the factor tree method of 48.

The steps on how to find the prime factorization of a composite number are:

1) Find any factor pair of the given number, and use these numbers to create two branches.
2) If a factor is prime, that branch is complete. Circle the prime.
3) If a factor is not prime, write it as the product of a factor pair and continue the process.
4) Write the composite number as the product of all the circled primes.
