Let this free LCD calculator find the least common denominator of each and every kind of fractions combination. The most important purpose of this lowest common denominator calculator is to create ease for you while you perform arithmetic operations on LCD fractions.
Well enough! Letâ€™s revise the concept of the lowest common denominator in brief detail.
“The smallest number that can be considered as the common denominator for a couple of fractions or more is called LCD.”
Basically, the common denominator is actually the multiple of each fractionâ€™s denominator in a set. The free LCD calculator looks for this common number and displays it on your screen in seconds.
The least denominator is the second name used for the least common multiple that you can find using various methods.
Moreover, we will be discussing the summary of all methods in a couple of steps below:
The free LCD calculator also follows all the above-mentioned terms and conditions to find the common denominator.
Here we have a table that goes for showing the smallest common denominators for various fraction combinations:

You can pick any fraction set from the above table and validate the results by the assistance of our free to use LCD calculator.
What do you think about resolving a couple of examples to recall your concept? Letâ€™s do it together!
Example # 01:
How to find the LCD for the following set of fractions:
3, 1 2/3, 4/5, 5/8
Solution:
Here we have:
3 = 3/1
1 2/3 = 5/3
Now we will take all the denominators and find their LCD as follows:
1, 3, 5, 8
LCD = 120
Equivalent fractions with LCD:
3 = 3 * 120/120 = 360/120
1 2/3 = 1 2/3 * 40/40 = 200/120
4/5 = 4/5 *24/24 = 96/120
5/8 = 5/8 * 15/15 = 75/120
So we have:
Equivalent Fractions = 360/120, 200/120, 96/120, 75/120
You can also commence this free to use least common denominator calculator to verify the authenticity of results.Â
Example # 02:
You are given the following combination of fractions:
3/5, 6/3, 6/2, 3/9, 4
How to find least common denominator for this LCD fractions combination.
Solution:
Here:
4 = 4/1
Here we have the denominators as follows:
5, 3, 2, 9, 1
Fraction common denominator = 90
Equivalent fractions with LCD:
3/5 = 3/5 * 18/18 = 54/90
6/3 = 6/3 * 30/30 = 180/90
6/2 = 6/2 * 45/45 = 270/90
3/9 = 3/9 * 10/10 = 30/90
4 = 4/1 * 90/90 = 360/90
So we have:
Equivalent Fractions = 54/90, 180/90, 270/90, 30/90, 360/90
This least common denominator calculator takes into consideration integers, fractions, or mixed numbers to determine the smallest common positive integer number. Letâ€™s have a look at its operation!
Input:
Output:
The free common denominator finder finds:
The smallest common denominator for given fractions is 40 that you could also cross check by using an LCD calculator.
The LCD for the given fraction combination is 63.
Yes, of course! You can consider LCD as the special case of LCM. The LCD is the LCM but it is true for the denominators of the fractions.
A particular number that is actually the multiple of all the numerators of fractions involved in a set is called their common numerator.
If we have the fractions with unlike denominators, then the only way to compare them is figuring out their LCD. Moreover, the fastest method to compare them is using an online least common denominator calculator.
As these are fractions with common denominators, so their LCD will also be 7.
Letâ€™s suppose that you have a couple of fractions that have the same numerators, always remember that the fraction with the bigger denominator is considered the smaller one. On the other hand, the fraction with the smaller denominator is the one that is bigger.
The fractions having different denominators are said to be unlike fractions.
10/60 is the smallest fraction in the world. This is because 10/60 = 1/6 = 0.16666â€¦
The main focus of determining the LCD is to simplify the addition, subtraction, multiplication, and division of fractions. This is why our best LCD calculator is the most fast and reliable way of finding the lowest common denominator of fractions set. It will help you resolve fraction problems more authentically.
