You need to know the least common denominator (LCD) of 76 and 8 if you want to add or subtract two fractions with 76 and 8 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 76 and 8 is 152.
Here is a math problem example where you need to know the LCD of 76 and 8 to solve:
3/76 + 2/8 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
152/76 = 2
