You need to know the least common denominator (LCD) of 32 and 51 if you want to add or subtract two fractions with 32 and 51 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 32 and 51 is 1632.
Here is a math problem example where you need to know the LCD of 32 and 51 to solve:
3/32 + 2/51 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
1632/32 = 51
1632/51 = 32
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 51 = 153
2 x 32 = 64
Step 3) Put it all together to solve the problem:
153/1632 + 64/1632 = 217/1632
= 3/32 + 2/51 = 217/1632
It's that easy! Once again, the lowest common denominator (LCD) of 32 and 51 is as follows:
1632
