You need to know the least common denominator (LCD) of 51 and 76 if you want to add or subtract two fractions with 51 and 76 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 51 and 76 is 3876.
Here is a math problem example where you need to know the LCD of 51 and 76 to solve:
3/51 + 2/76 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
3876/51 = 76
3876/76 = 51
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 76 = 228
2 x 51 = 102
Step 3) Put it all together to solve the problem:
228/3876 + 102/3876 = 330/3876
= 3/51 + 2/76 = 330/3876
It's that easy! Once again, the lowest common denominator (LCD) of 51 and 76 is as follows:
3876
