You need to know the least common denominator (LCD) of 62 and 7 if you want to add or subtract two fractions with 62 and 7 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 62 and 7 is 434.
Here is a math problem example where you need to know the LCD of 62 and 7 to solve:
3/62 + 2/7 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
434/62 = 7
434/7 = 62
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 7 = 21
2 x 62 = 124
