To find the least common denominator, list out the multiples of both denominators until you find the smallest multiple
How do you find the LCD?
In order to use the greatest common factor to solve the problem, you must first multiply the two denominators together. Divide this product by the GCF. After finding the product of the two denominators, divide that product by the GCF you found previously . This number will be your least common denominator (LCD).
