You need to know the least common denominator (LCD) of 3 and 62 if you want to add or subtract two fractions with 3 and 62 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 3 and 62 is 186.
Here is a math problem example where you need to know the LCD of 3 and 62 to solve:
3/3 + 2/62 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
186/3 = 62
186/62 = 3
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 62 = 186
2 x 3 = 6
Step 3) Put it all together to solve the problem:
186/186 + 6/186 = 192/186
= 3/3 + 2/62 = 192/186
It's that easy! Once again, the lowest common denominator (LCD) of 3 and 62 is as follows:
186
