You need to know the least common denominator (LCD) of 63 and 50 if you want to add or subtract two fractions with 63 and 50 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 63 and 50 is 3150.
Here is a math problem example where you need to know the LCD of 63 and 50 to solve:
3/63 + 2/50 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
3150/63 = 50
3150/50 = 63
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 50 = 150
2 x 63 = 126
Step 3) Put it all together to solve the problem:
150/3150 + 126/3150 = 276/3150
= 3/63 + 2/50 = 276/3150
It's that easy! Once again, the lowest common denominator (LCD) of 63 and 50 is as follows:
3150
