Not much. The process to find them is the same. To find an LCM, compare at least two integers. To find an LCD, compare at least two integers that are denominators.

the lcd is the least common denominator but the LCM is the least common multiple.


None, really. The process is the same. To find the least common denominator between 3/5 and 4/7, find the LCM of 5 and 7.


It is possible for two fractions to have many common denominators. The smallest of these is the LCD.


They are essentially the same. A common denominator is the common multiple of a set of denominators of a set of fractions.






The least common denominator is the least common multiple of the denominators of the fractions.


Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.


Common denominators are common multiples of two or more denominators.


The common denominator refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The common denominator for a number is any non-zero multiple of the number.


The common denominator refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The common denominator for a number is any non-zero multiple of the number.

A common denominator is 209, as is any multiple of 209.




The Least (or Lowest) Common Multiple (LCM) is the smallest number that is a multiple of both numbers. For example: the LCM of 10 and 4 is 20, because both 10 and 4 go into 20 and 20 is the smallest number both 10 and 4 can go into. To be able to add or subtract fractions they must have the same denominator. If the denominators are different then the fractions must first be converted into equivalent fractions with a common denominator; any common denominator can be used, but by using the Least Common Multiple of the denominators as the new denominator it keeps the numbers smaller; this smallest denominator is known as the Least Common Denominator Thus the Least Common Denominator is the Least Common Multiple of the denominators of two (or more) fractions (used when adding or subtracting fractions with different denominators). As the Least Common Multiple is used most often with adding or subtracting fractions, it is often referred to as the Least Common Denominator (because the numbers being considered are usually denominators of fractions).


The least common denominator is 1. The greatest common denominator is 2. The least common multiple is 1,218.


Both result from the comparison of integers. The process used to find them is the same. The only difference is in their function. One is a denominator, one isn't.


The least common denominator of two fractions is the least common multiple of the two denominators.
