# Ch 20: Factoring

Learn how to factor out variables, find the least common multiples and use prime factorization in preparation for the 2014 GED Mathematical Reasoning exam. Video lessons and practice quizzes can provide you with the types of questions you'll find on the mathematical reasoning section of the 2014 GED exam.

## 2014 GED Mathematical Reasoning Exam: Factoring - Chapter Summary

This chapter starts with a discussion of the purpose of factoring. Later lessons cover prime factorizations and equivalent fraction expressions. You'll also learn how to reduce fractions by dividing and factor by grouping. By the end of the chapter, you'll be ready to take the 2014 GED Mathematical Reasoning exam. Lesson topics covered in the chapter include:

• Prime factorization
• Least common multiples
• Equivalent expressions
• Fraction notation
• Factoring by grouping

This chapter on factoring contains several examples, including information on how to check your factoring work. The lessons are concise and easy to understand, with self-assessment quizzes that allow you to test your learning. These sample problems resemble the actual questions you may find on the 2014 GED Mathematical Reasoning exam.

### 2014 GED Mathematical Reasoning Exam Objectives

The updated 2014 GED exam is now entirely computer based and is designed to adhere to the Common Core State Standards. The exam seeks to assess your comprehension of common core high school academic standards in four different subjects that include mathematical reasoning. The questions on the mathematical reasoning test are divided among algebraic problem solving problems, which account for 55% of the test, and quantitative problem solving questions, which constitute 45% of the exam. The objectives of this chapter on factoring include:

• Finding the prime factorization of a number
• Using factorization to find the least common multiples
• Producing an equivalent expression by multiplying by 1
• Simplifying fraction notations
• Factoring out variables in an expression
• Reducing factors using division
• Factoring by grouping

You'll have 90 minutes to take the 2014 GED Mathematical Reasoning exam. The test is made up of multiple choice, fill-in-the-blank, hot spot and drag-and-drop questions. The mathematical reasoning exam first requires you to finish a five-question section without a calculator, then moves on to a longer second section that may be completed with the help of a computer calculator.
