What you will learn! 1. How to find the LCM of two or more numbers. 2. How to find the LCD of two or more fractions.

Multiple Common Multiple Least common multiple Least common denominator

What you really need to know! The least common multiple (LCM) is the least nonzero number that is a multiple of the given numbers.

What you really need to know! The least common denominator (LCD) of two or more fractions is the LCM of the denominators.

LCM = 2  2  2  3  3 = 72 8 = 2  2  2 18 = 2  3  3 Example: Find the LCM of 8 and

Example 1: Find the LCM of 24 and = 72

Example 2: Find the LCM of 168 and = 2,520

Example 3: Find the LCM of 12x 2 y 2 and 6y 3 223xxyyy=12x 2 y 3

Example 4: Find the LCD of 7/8 and 13/20 : 2225=40

Example 5: Find the LCD of 9/36a 2 b and 16/27ab 2 : 22333aabb = 108a 2 b 2

Example 6: Replace the ? with, or =.
