You need to know the least common denominator (LCD) of 53 and 2 if you want to add or subtract two fractions with 53 and 2 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 53 and 2 is 106.
Here is a math problem example where you need to know the LCD of 53 and 2 to solve:
3/53 + 2/2 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
106/53 = 2
106/2 = 53
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 53 = 106
Step 3) Put it all together to solve the problem:
6/106 + 106/106 = 112/106
= 3/53 + 2/2 = 112/106
It's that easy! Once again, the lowest common denominator (LCD) of 53 and 2 is as follows:
106
