the least common denominator
The smallest number that each of the denominators will divide into evenly is called the least common multiple (LCM).
It is the smallest positive integer which is a multiple of the denominators of each fraction.
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).
in order to answer this problem you have to first make the denominators (bottom number) match.Do this by finding the smallest common multiple (the smallest number that both of the denominators divide into) of the denominators.3/4 - 1/23/4 - (1/2) x 2 (4 is the smallest common multiple of 2 and 4. Multiply 1/2 by 2 so that the denominators match)3/4 - 2/4 (now you just subtract the numerators (top number). leave the denominators as they are.)3/4 - 2/4 = 1/4
A multiple of the denominator.
The smallest number that each of the denominators will divide into evenly is called the least common multiple (LCM).
The smallest number that can be divided by two or more different denominators is the "least common multiple" or LCM of those numbers.
It is the lowest common multiple of the different denominators.
It is the smallest positive integer which is a multiple of the denominators of each fraction.
The least common denominator is the least common multiple of the denominators.
The least common multiple of the denominators is knows as the LCD or least common denominator.
The Least Common Denominator (LCD) or Least Common Multiple (LCM)
Assuming those are denominators of fractions you wish to add or subtract, you can use any common multiple of 4 and 14; the Lowest Common Multiple (LCM), often called the Lowest Common Denominator (LCD) especially when when referring to the denominators of fraction, provides the smallest numerators. For 4 and 14, the LCM is 28.
This is called the least common denominator.
common denominator
Common denominators are common multiples of two or more denominators.
It's called the Least Common Multiple. (LCM)
