Least Common Denominator (LCD) of 33, 38, and 69




The Least Common Denominator of 33, 38 and 69, also known as the Lowest Common Denominator of 33, 38 and 69, is useful if you need to add, subtract, or compare three fractions with the denominators of 33, 38 and 69.

The fractions with 33, 38 and 69 denominators will look like this:

   
X
 
   
33
 
   
   
Y
 
   
38
 
   
   
Z
 
   
69
 

The Least Common Denominator of 33, 38 and 69 is 28842.


You need to multiply 33 by 874, 38 by 759, and 69 by 418 to make them all 28842. 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 874
 
   
33 x 874
 
   
   
Y x 759
 
   
38 x 759
 
   
   
Z x 418
 
   
69 x 418
 

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

   
874X
 
   
28842
 
   
   
759Y
 
   
28842
 
   
   
418Z
 
   
28842
 

You can substitute X, Y and Z with the numerators of your fractions with 33, 38 and 69 denominators. This way you can add, subtract and compare your fractions correctly.
