Assignment: Factors Choice
Today you chose an assignment based upon your comfort level with factoring. Below each assignment is a note -
1) Lesson 2.1
Make sure you list ALL of the factors for a number, including 1 and the number. We went over factors today (at the same time we discussed it as related to fractions) ... they are not decimals! Then list the common factors between the two numbers, finally writing the greatest common factor (the largest number they both have as factors) in the last blank. This is just good, solid practice that you should become quick at.
2) Factor Trees
This worksheet shows you how to make a factor tree for a number. The factor tree contains factors for the original number, but in the end you have only the prime factors left. Sometimes it takes awhile to build a tree and sometimes it happens quickly. But always build the tree; I recommend circling the prime factors you end up with, but this is not required as long as I can read your tree.
*And yes, there is more than one way to build a tree!
3) Prime Factorization
Once you know how to create a factor tree, you can do lots of things with them. One of those things is to create a prime factorization for the original number. Every number has a prime factorization meaning that it can be built (through multiplication) using only prime numbers.
On this assignment, you should build your tree first, then circle the prime numbers as I did in red for you. Rewrite those on the line (as in the example: 2 x 3 x 5. The next step is to find GCFs and LCMs using prime factorizations ... it's pretty cool!
