The common denominator of any two or more whole numbers will always be one (1) because common denominators refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1,which will always yield a denominator of 1.
Any multiple of 6.
It is 36 which is also their LCM
The LCD of the given three numbers is 18
6
12
The least common denominator of a set of numbers is basically the least common multiple of a set of numbers.Therefore, with 9 and 3, the LCM/ LCD is 9 because 9 is the 3rd multiple of 3.
126
the least common multiple of 15,9,and 12 is 180.
It is: 90
45
3
what is a common denominator for 6, 9 and 3
9 is the common denominator. 2/3 = 6/9.
It is 3
It is 36.
36
18 3*6 = 18 2*9 = 18
Any multiple of 36.
You can find a common denominator of any set of denominators by multiplying them together. That result will not necessarily be the lowest common denominator. Example: 1/6 and 1/9 6 x 9 = 54 and 54 is a common denominator of 6 and 9, but the LCD is 18.
9
A single number can not have a "common denominator", because a "common denominator" is a denominator which can be used to express both numbers. For example 1 / 2 and 1/3 have common denominators: 6, 12, 18, 24, 30, 36, etc... because you can express 1/2 as 3/6, 6/12, 9/18, 12/24, 15/30, 18/36 etc... and you can also express 1/3 as 2/6, 6/18, 8/24, 10/30, 12/36 etc... A non example is 9, which is NOT a common denominator of 1/2 and 1/3, because while you can express 1/3 as 3/9, 1/2 with a denominator of 9 would be 4.5/9, which is not a proper fraction.
The lowest common denominator of 6 and 9 is three.
