You need to know the least common denominator (LCD) of 43 and 37 if you want to add or subtract two fractions with 43 and 37 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 43 and 37 is 1591.
Here is a math problem example where you need to know the LCD of 43 and 37 to solve:
3/43 + 2/37 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
