The lowest common denominator or least common denominator (abbreviated LCD) is
the least common multiple of the denominators of a set of fractions. It is the smallest
number that is a multiple of the denominators.
the least common multiple of the denominators of a set of fractions. It is the smallest
number that is a multiple of the denominators.
Lowest common denominator
For instance, the LCD of
is 36 because the least common multiple of
12 and 18 is 36.
12 and 18 is 36.
What is the Least Common Multiple (LCM)?
The Least Common Multiple (LCM) of a set of numbers is the smallest number into
which each of the numbers of the set, will divide evenly.
which each of the numbers of the set, will divide evenly.
Example: 1:What is the Least Common Multiple of 2, 9, and 6?
Solution: The LCM of 2, 9, 6 = 18
| Lowest common denominator (LCD) |
Example: whats the LCD of
the LCD is 12.
Factors are numbers that divide evenly in a number. The greatest common factor
of two or more numbers is the largest number that can divide evenly into each of
the numbers.
