You need to know the least common denominator (LCD) of 73 and 2 if you want to add or subtract two fractions with 73 and 2 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 73 and 2 is 146.
Here is a math problem example where you need to know the LCD of 73 and 2 to solve:
3/73 + 2/2 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
146/73 = 2
146/2 = 73
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 73 = 146
Step 3) Put it all together to solve the problem:
6/146 + 146/146 = 152/146
= 3/73 + 2/2 = 152/146
It's that easy! Once again, the lowest common denominator (LCD) of 73 and 2 is as follows:
146
