You need to know the least common denominator (LCD) of 6 and 43 if you want to add or subtract two fractions with 6 and 43 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 6 and 43 is 258.
Here is a math problem example where you need to know the LCD of 6 and 43 to solve:
3/6 + 2/43 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
258/6 = 43
258/43 = 6
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 43 = 129
2 x 6 = 12
Step 3) Put it all together to solve the problem:
129/258 + 12/258 = 141/258
= 3/6 + 2/43 = 141/258
It's that easy! Once again, the lowest common denominator (LCD) of 6 and 43 is as follows:
258
