Least Common Denominator (LCD) of 19, 26, and 84




The Least Common Denominator of 19, 26 and 84, also known as the Lowest Common Denominator of 19, 26 and 84, is useful if you need to add, subtract, or compare three fractions with the denominators of 19, 26 and 84.

The fractions with 19, 26 and 84 denominators will look like this:

   
X
 
   
19
 
   
   
Y
 
   
26
 
   
   
Z
 
   
84
 

The Least Common Denominator of 19, 26 and 84 is 20748.


You need to multiply 19 by 1092, 26 by 798, and 84 by 247 to make them all 20748. Furthermore, you need to multiply the numerators by the same amounts to keep the fraction values the same.

Therefore, you have to make the following calculations so the fractions keep the same value and get the same denominator:

   
X x 1092
 
   
19 x 1092
 
   
   
Y x 798
 
   
26 x 798
 
   
   
Z x 247
 
   
84 x 247
 

Which gives you the following three new fractions that you can add, subtract and compare:

   
1092X
 
   
20748
 
   
   
798Y
 
   
20748
 
   
   
247Z
 
   
20748
 

You can substitute X, Y and Z with the numerators of your fractions with 19, 26 and 84 denominators. This way you can add, subtract and compare your fractions correctly.
