You need to know the least common denominator (LCD) of 62 and 9 if you want to add or subtract two fractions with 62 and 9 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 62 and 9 is 558.
Here is a math problem example where you need to know the LCD of 62 and 9 to solve:
3/62 + 2/9 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
558/62 = 9
