You need to know the least common denominator (LCD) of 80 and 41 if you want to add or subtract two fractions with 80 and 41 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 80 and 41 is 3280.
Here is a math problem example where you need to know the LCD of 80 and 41 to solve:
3/80 + 2/41 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
3280/80 = 41
3280/41 = 80
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 41 = 123
2 x 80 = 160
Step 3) Put it all together to solve the problem:
123/3280 + 160/3280 = 283/3280
= 3/80 + 2/41 = 283/3280
It's that easy! Once again, the lowest common denominator (LCD) of 80 and 41 is as follows:
3280
