You need to know the least common denominator (LCD) of 22 and 53 if you want to add or subtract two fractions with 22 and 53 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 22 and 53 is 1166.
Here is a math problem example where you need to know the LCD of 22 and 53 to solve:
3/22 + 2/53 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
1166/22 = 53
1166/53 = 22
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 53 = 159
2 x 22 = 44
Step 3) Put it all together to solve the problem:
159/1166 + 44/1166 = 203/1166
= 3/22 + 2/53 = 203/1166
It's that easy! Once again, the lowest common denominator (LCD) of 22 and 53 is as follows:
1166
