You need to know the least common denominator (LCD) of 36 and 71 if you want to add or subtract two fractions with 36 and 71 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 36 and 71 is 2556.
Here is a math problem example where you need to know the LCD of 36 and 71 to solve:
3/36 + 2/71 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
2556/36 = 71
2556/71 = 36
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 71 = 213
2 x 36 = 72
Step 3) Put it all together to solve the problem:
213/2556 + 72/2556 = 285/2556
= 3/36 + 2/71 = 285/2556
It's that easy! Once again, the lowest common denominator (LCD) of 36 and 71 is as follows:
2556
