You need to know the least common denominator (LCD) of 19 and 6 if you want to add or subtract two fractions with 19 and 6 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 19 and 6 is 114.
Here is a math problem example where you need to know the LCD of 19 and 6 to solve:
3/19 + 2/6 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
114/19 = 6
114/6 = 19
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 6 = 18
2 x 19 = 38
Step 3) Put it all together to solve the problem:
18/114 + 38/114 = 56/114
= 3/19 + 2/6 = 56/114
It's that easy! Once again, the lowest common denominator (LCD) of 19 and 6 is as follows:
114
