You need to know the least common denominator (LCD) of 67 and 32 if you want to add or subtract two fractions with 67 and 32 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 67 and 32 is 2144.
Here is a math problem example where you need to know the LCD of 67 and 32 to solve:
3/67 + 2/32 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
2144/67 = 32
2144/32 = 67
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 32 = 96
2 x 67 = 134
Step 3) Put it all together to solve the problem:
96/2144 + 134/2144 = 230/2144
= 3/67 + 2/32 = 230/2144
It's that easy! Once again, the lowest common denominator (LCD) of 67 and 32 is as follows:
2144
