You need to know the least common denominator (LCD) of 73 and 4 if you want to add or subtract two fractions with 73 and 4 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 73 and 4 is 292.
Here is a math problem example where you need to know the LCD of 73 and 4 to solve:
3/73 + 2/4 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
292/73 = 4
292/4 = 73
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 4 = 12
2 x 73 = 146
Step 3) Put it all together to solve the problem:
12/292 + 146/292 = 158/292
= 3/73 + 2/4 = 158/292
It's that easy! Once again, the lowest common denominator (LCD) of 73 and 4 is as follows:
292
