Essential Question • LEQ: What is the purpose of exponential notation • LEQ: LEQ: How do I show the factor form of a number expressed in exponential notation?
Exponential Form • Numbers can be written different ways. These are the different ways that we can write numbers. • Word Form- One Hundred million • Standard form (number form) -100,000,000 • Expanded Form of 12,356(1 x 10,000) + (2 x 1,000) + (3 x 100) + ( 5 x 10) + (6 x 1) 4 • Exponential form – 10 • Factor Form- 10 x 10 x 10 x 10 = • Scientific Form 6.4 x 109 = 6,400,000,000
Prime vs. Composite #’s • Prime Number: A number that has exactly two factors. • Composite Number: A number that has more than one factor. • Note: 1 is a number that is neither prime nor composite.
Greatest Common Factor • Factors are numbers that multiply to make a number. Example: • Factors of 10 : 1, 2, 5, 10 • Factors of 15: 1, 3, 5, 15 The Greatest Common Factor or GCF is the largest factor that 2 or more numbers have in common. In this example, 5 is the greatest common factor.
Least Common Multiple • Multiples are the product of two numbers, Multiples for a specific number are infinite. For example: The first five multiples of 5 are: 5, 10, 15, 20, 25. The first five multiples of 4 are: 4, 8, 12, 16, 20. The Least Common Multiple or LCM is the smallest multiple that two or more numbers have in common. In this example, 20 is the LCM.
