You need to know the least common denominator (LCD) of 79 and 6 if you want to add or subtract two fractions with 79 and 6 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 79 and 6 is 474.
Here is a math problem example where you need to know the LCD of 79 and 6 to solve:
3/79 + 2/6 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
