You need to know the least common denominator (LCD) of 8 and 97 if you want to add or subtract two fractions with 8 and 97 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 8 and 97 is 776.
Here is a math problem example where you need to know the LCD of 8 and 97 to solve:
3/8 + 2/97 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
776/8 = 97
776/97 = 8
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 97 = 291
2 x 8 = 16
Step 3) Put it all together to solve the problem:
291/776 + 16/776 = 307/776
= 3/8 + 2/97 = 307/776
It's that easy! Once again, the lowest common denominator (LCD) of 8 and 97 is as follows:
776
