You need to know the least common denominator (LCD) of 3 and 58 if you want to add or subtract two fractions with 3 and 58 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 3 and 58 is 174.
Here is a math problem example where you need to know the LCD of 3 and 58 to solve:
3/3 + 2/58 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
174/3 = 58
174/58 = 3
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 58 = 174
2 x 3 = 6
Step 3) Put it all together to solve the problem:
174/174 + 6/174 = 180/174
= 3/3 + 2/58 = 180/174
It's that easy! Once again, the lowest common denominator (LCD) of 3 and 58 is as follows:
174
