You need to know the least common denominator (LCD) of 67 and 62 if you want to add or subtract two fractions with 67 and 62 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 67 and 62 is 4154.
Here is a math problem example where you need to know the LCD of 67 and 62 to solve:
3/67 + 2/62 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
4154/67 = 62
4154/62 = 67
