You need to know the least common denominator (LCD) of 58 and 13 if you want to add or subtract two fractions with 58 and 13 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 58 and 13 is 754.
Here is a math problem example where you need to know the LCD of 58 and 13 to solve:
3/58 + 2/13 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
754/58 = 13
