You need to know the least common denominator (LCD) of 63 and 4 if you want to add or subtract two fractions with 63 and 4 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 63 and 4 is 252.
Here is a math problem example where you need to know the LCD of 63 and 4 to solve:
3/63 + 2/4 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
252/63 = 4
252/4 = 63
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 4 = 12
2 x 63 = 126
Step 3) Put it all together to solve the problem:
12/252 + 126/252 = 138/252
= 3/63 + 2/4 = 138/252
It's that easy! Once again, the lowest common denominator (LCD) of 63 and 4 is as follows:
252
