You need to know the least common denominator (LCD) of 73 and 3 if you want to add or subtract two fractions with 73 and 3 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 73 and 3 is 219.
Here is a math problem example where you need to know the LCD of 73 and 3 to solve:
3/73 + 2/3 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
219/73 = 3
219/3 = 73
