Method:
 If there are unlike fractions, then the denominator is made common.
 This is also referred to as the Least Common Multiple.
 List out the multiples of each of the denominators.
 Find out the common multiples and the least of them is the LCD.
Example: 1/3, 3/5
Multiples of 3 = 3, 6, 9, 12, 15, 18....
Multiples of 5 = 5, 10, 15, 20......
Common multiple = 15
Hence LCM = 15
Answer: 15
Directions: Find the LCD of the following. Also write at least 5 examples of your own.
