You need to know the least common denominator (LCD) of 6 and 83 if you want to add or subtract two fractions with 6 and 83 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 83 is 498.
Here is a math problem example where you need to know the LCD of 6 and 83 to solve:
3/6 + 2/83 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
498/6 = 83
498/83 = 6
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 83 = 249
2 x 6 = 12
