Learn to find the lowest common denominator (LCD) of three or more fractions
Use prime factorization in order to find these common denominators.
The lowest common denominator ( LCD ) is the smallest number that the denominators will divide into evenly.
For example, the LCD of 2,4, 8 is 8 because all three numbers will divide evenly into this number.
