You need to know the least common denominator (LCD) of 70 and 59 if you want to add or subtract two fractions with 70 and 59 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 70 and 59 is 4130.
Here is a math problem example where you need to know the LCD of 70 and 59 to solve:
3/70 + 2/59 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
4130/70 = 59
4130/59 = 70
