The least common multiple (lcm) is used to find an equivalent fraction in order to add or subtract fractions. If your problem is 1/3 +1/2 you have to use the multiples to find the common denominator The multiples of 3 are 3,6,9,12,15,... The multiples of 2 are 2,4,6,8,10,... The least common multiple of those two numbers is 6 so I would say 1/3 = 2/6 and 1/2 = 3/6. Now you could add the two fractions since they have a common denominator. 2/6 + 3/6 = 5/6

What is a sentence for least common multiple?
The least common multiple of 6 and 9 is 18.
What is the relationship between the Least Common Multiple and the Least Common Denominator?
They're essentially the same thing. At least, the same process is used to find them. The function of the number is the only thing that's different. For the LCD, the whole number is part of a fraction.
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 smallest common multiples is called?
It is usually called the least common multiple. But it can also be called the least/lowest common denominator when it is used for addition or subtraction of rational fractions.
What is the least common multiple of 40?
A single number cannot have a lowest common multiple - a lowest common multiple is used to compare two or more different numbers.
What is the least common multiple used for?
It helps with the adding and subtracting of fractions.
What is the least common multiple of 3 4 5 6 7?
A lowest common multiple is used to compare two or more numbers. A lowest common multiple cannot be used for a single number.
How you use the least common multiple?
When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.
What 2 operations are used with lowest common denominator?
The least common denominator or (LCD) of two or more fractions is the least common multiple of the denominators.
What is 125 the least common multiple of?
A single number cannot have a Lowest Common Multiple. A Lowest Common Multiple is used to compare two or more numbers.
What is the least common multiple of ten?
You need at least two numbers to find an LCM.
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).
