You need to know the least common denominator (LCD) of 52 and 97 if you want to add or subtract two fractions with 52 and 97 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 52 and 97 is 5044.
Here is a math problem example where you need to know the LCD of 52 and 97 to solve:
3/52 + 2/97 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
5044/52 = 97
5044/97 = 52
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 97 = 291
2 x 52 = 104
Step 3) Put it all together to solve the problem:
291/5044 + 104/5044 = 395/5044
= 3/52 + 2/97 = 395/5044
It's that easy! Once again, the lowest common denominator (LCD) of 52 and 97 is as follows:
