How to calculate the least common denominator ( LCD )?
One way to understand the least common denominator is to list all whole numbers that are multiples of the two denominators. For example, for the fractions 1/3 and 2/5 the denominators are 3 and 5. The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33… The multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50…
Which is the least common denominator for 2, 8, 6, 1?
For the denominators (2, 8, 6, 1) the least common multiple (LCM) is 24. Therefore, the least common denominator (LCD) is 24. Rewriting the original inputs as equivalent fractions with the LCD:
How to calculate fractions with lowest common denominator?
Example: for LCD calculation of three fractions 1/2 2/3 5/4 enter 1/2 2/3 5/4. The same fraction can be expressed in many different forms. If the ratio between numerator and denominator is the same, the fractions represent the same rational number.
