You need to know the least common denominator (LCD) of 41 and 4 if you want to add or subtract two fractions with 41 and 4 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 41 and 4 is 164.
Here is a math problem example where you need to know the LCD of 41 and 4 to solve:
3/41 + 2/4 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
164/41 = 4
164/4 = 41
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 4 = 12
2 x 41 = 82
Step 3) Put it all together to solve the problem:
12/164 + 82/164 = 94/164
= 3/41 + 2/4 = 94/164
It's that easy! Once again, the lowest common denominator (LCD) of 41 and 4 is as follows:
164
