You need to know the least common denominator (LCD) of 94 and 19 if you want to add or subtract two fractions with 94 and 19 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 94 and 19 is 1786.
Here is a math problem example where you need to know the LCD of 94 and 19 to solve:
3/94 + 2/19 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
1786/94 = 19
1786/19 = 94
