You need to know the least common denominator (LCD) of 8 and 34 if you want to add or subtract two fractions with 8 and 34 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 8 and 34 is 136.
Here is a math problem example where you need to know the LCD of 8 and 34 to solve:
3/8 + 2/34 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
136/8 = 17
136/34 = 4
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 17 = 51
2 x 4 = 8
Step 3) Put it all together to solve the problem:
51/136 + 8/136 = 59/136
= 3/8 + 2/34 = 59/136
It's that easy! Once again, the lowest common denominator (LCD) of 8 and 34 is as follows:
136
