You need to know the least common denominator (LCD) of 8 and 76 if you want to add or subtract two fractions with 8 and 76 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 8 and 76 is 152.
Here is a math problem example where you need to know the LCD of 8 and 76 to solve:
3/8 + 2/76 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
152/8 = 19
152/76 = 2
Step 2) Multiply each nominator with the respective answers from Step 1:
