You need to know the least common denominator (LCD) of 8 and 61 if you want to add or subtract two fractions with 8 and 61 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 8 and 61 is 488.
Here is a math problem example where you need to know the LCD of 8 and 61 to solve:
3/8 + 2/61 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
488/8 = 61
488/61 = 8
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 61 = 183
2 x 8 = 16
Step 3) Put it all together to solve the problem:
183/488 + 16/488 = 199/488
= 3/8 + 2/61 = 199/488
It's that easy! Once again, the lowest common denominator (LCD) of 8 and 61 is as follows:
488
