Calculator Use

Use this Least Common Denominator Calculator to find the lowest common denominator ( LCD ) of fractions, integers and interracial numbers. Finding the LCD is crucial because fractions need to have the lapp denominator when you are doing addition or subtraction mathematics with fractions .

What is the Least Common Denominator?

The least common denominator ( LCD ) is the smallest number that can be a common denominator for a set of fractions. besides known as the lowest common denominator, it is the lowest number you can use in the denominator to create a typeset of equivalent fractions that all have the lapp denominator.

How to Find the
LCD of Fractions, Integers and Mixed Numbers:

To find the least common denominator first commute all integers and mix numbers ( shuffle fractions ) into fractions. then find the lowest coarse multiple ( LCM ) of the denominators. This act is like as the least common denominator ( LCD ) .You can then write each term as an equivalent fraction with the same LCD denominator.

Steps to find the
LCD of fractions, integers and mixed numbers

  1. Convert integers and mixed numbers to improper fractions
  2. Find the LCD of all the fractions
  3. Rewrite fractions as equivalent fractions using the
    LCD

Example Using the Lowest Common Denominator Calculator

Find the LCD of : 1 1/2, 3/8, 5/6, 3

  • Convert integers and mixed numbers to improper fractions.

    3/8 and 5/6 are already fractions so we can use those as they are written.

    1 1/2 is the same as (1/1) + (1/2). Using the formula for adding fractions, ((n1*d2)+(n2*d1)) / (d1*d2), we get ((1*2)+(1*1)) / (1*2) = 3/2.

    3 can be rewritten as a fraction as 3/1
  • Equivalent fractions are: 3/2, 3/8, 5/6, 3/1
  • Now find the least common denominator (LCD) (or the
    least common multiple (LCM) of the denominators)

    • LCD = 24
  • Rewriting the fractions as equivalent fractions using the
    LCD

    • 36/24, 9/24, 20/24, 72/24
