What is the Least Common Denominator of 5 and 66?
You need to know the least common denominator (LCD) of 5 and 66 if you want to add or subtract two fractions with 5 and 66 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 5 and 66 is 330.
Here is a math problem example where you need to know the LCD of 5 and 66 to solve:
3/5 + 2/66 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
330/5 = 66
330/66 = 5
