What is the Least Common Denominator of 5 and 69?
You need to know the least common denominator (LCD) of 5 and 69 if you want to add or subtract two fractions with 5 and 69 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 5 and 69 is 345.
Here is a math problem example where you need to know the LCD of 5 and 69 to solve:
3/5 + 2/69 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
345/5 = 69
345/69 = 5
Step 2) Multiply each nominator with the respective answers from Step 1:
