What is the Least Common Denominator of 6 and 70?
You need to know the least common denominator (LCD) of 6 and 70 if you want to add or subtract two fractions with 6 and 70 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 70 is 210.
Here is a math problem example where you need to know the LCD of 6 and 70 to solve:
3/6 + 2/70 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
210/6 = 35
210/70 = 3
