Friday January 6, 2011

Today we introduced prime authorization by drawing a factor tree. Also I checked for a completion of last nights homework. There were many students who did not complete the homework. It can still be turned in next week for a late grade.

To perform prime factorization, we talked about five steps

1. Start with number we are factoring
2. Draw 2 branches down from the number
3. Choose 2 factors whose product is equal to the number
4. Continue to split numbers until prime numbers are reached. Circle each prime number.
5. When there are only prime (circled) numbers left, stop drawing branches.

Your answer is the product of all of the circled (prime) numbers. Be sure to write in exponential form!
