What is the difference between a least common multiple and a least common denominator?
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).
What is the least common denominator for 18 and 25?
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
What is the Least Common Denominator of 29 and 80?
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
What is a least common denominator for 6 and 8?
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
What is the least common denominator of 12 and 13?
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
What are the least common multiple of a denominator called?
The least common denominator.
What is the least common denominator of two fractions?
The least common denominator is the least common multiple of the denominators of the fractions.
What is the least common multiple of two ir more denominators?
That's the least common denominator or LCD.
What makes the least common denominator the most efficient common denominator in addition o subtraction?
It is the lowest common multiple of the different denominators.
Is the least common multiple of the denominators?
The least common denominator is the least common multiple of the denominators.
The smallest number that can be divided by two or more different demoninators?
The least common denominator or the least common multiple.
What is the least common multiple of the denominator of two or more fractions is their?
least common denominator
What is the least common multiple of two or more denominator?
That's the least common denominator.
What is the smallest number that can be divided by two or more different denominator is called?
The smallest number that can be divided by two or more different denominators is the "least common multiple" or LCM of those numbers.
What is least common multiple used for?
When adding or subtracting fractions with different denominators then the least common multiple amongst them is needed to find the lowest common denominator.
What is the least common denominator of 42 and 58?
The least common denominator is 1. The greatest common denominator is 2. The least common multiple is 1,218.
