LCM-Smallest expression that is a multiple of each expression in the set

What is the LCM of 7 and 5?

What is the LCM of 8x and 2xy?

What is the LCM of 5x2y4 and 3x3y2?

What is the LCM of x2- y2 and 2x - 2y? (hint-factor first)

To add fractions with unlike denominators you will need to find the LCM of the denominators to get a common denominator. (This will be tomorrow's lesson)
