You need to know the least common denominator (LCD) of 41 and 86 if you want to add or subtract two fractions with 41 and 86 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 41 and 86 is 3526.
Here is a math problem example where you need to know the LCD of 41 and 86 to solve:
3/41 + 2/86 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
3526/41 = 86
3526/86 = 41
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 86 = 258
2 x 41 = 82
Step 3) Put it all together to solve the problem:
258/3526 + 82/3526 = 340/3526
= 3/41 + 2/86 = 340/3526
It's that easy! Once again, the lowest common denominator (LCD) of 41 and 86 is as follows:
3526
