You need to know the least common denominator (LCD) of 26 and 4 if you want to add or subtract two fractions with 26 and 4 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 26 and 4 is 52.
Here is a math problem example where you need to know the LCD of 26 and 4 to solve:
3/26 + 2/4 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
52/26 = 2
52/4 = 13
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 2 = 6
2 x 13 = 26
Step 3) Put it all together to solve the problem:
6/52 + 26/52 = 32/52
= 3/26 + 2/4 = 32/52
It's that easy! Once again, the lowest common denominator (LCD) of 26 and 4 is as follows:
52
