You need to know the least common denominator (LCD) of 62 and 4 if you want to add or subtract two fractions with 62 and 4 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 62 and 4 is 124.
Here is a math problem example where you need to know the LCD of 62 and 4 to solve:
3/62 + 2/4 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
124/62 = 2
124/4 = 31
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 31 = 62
Step 3) Put it all together to solve the problem:
6/124 + 62/124 = 68/124
= 3/62 + 2/4 = 68/124
It's that easy! Once again, the lowest common denominator (LCD) of 62 and 4 is as follows:
124
