The lowest common denominator of any two or more whole numbers, such as 12 7 9 and 6, will always be one (1) because 'common denominator' 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.

How do you make 6 and 7 have a common denominator?
The easiest way to find a common denominator of two numbers is to multiply them. Therefore, one of the common denominators for 6 and 7 would be 42 (7 x 6). This method will not necessarily produce the lowest common denominator, but it will determine one. For example, multiplying 4 and 6 will give you 24 as a common denominator. However, the lowest common denominator for 4 and 6 is 12.
Least common denominators?

How do you subtract fractions with different denominators and then put in simplest form?
You need to find a common denominator for the two fractions, then you can subtract them. Most will find the lowest common denominator (LCD) which is the same as the lowest common multiple of the two denominators, but any common denominator will work. You can get a common denominator, by multiplying the two numbers together, for example, but it might not be the lowest.Here's an example: 1/2 - 1/6 --> a common denominator is 2 x 6 = 12, but knowing how to find the lowest common denominator, you find LCD = 6.Either one will work though. Take 12: we need to convert each fraction to an equivalent fraction that has 12 in the denominator. So for 1/2, we need to multiply 2 by a number to get 12 [12/2 = 6], so we multiply top and bottom by 6, and get 6/12.For 1/6, multiply 6 by 2 is 12, and the top: 1 times 2 = 2 --> 2/12.Now we have 6/12 - 2/12. The denominators are the same, so subtract the numerators: 6 - 2 = 4, so we have 4/12.Now simplify: Factor out and see what common factors between 4 and 12 can be canceled. So 12 = 3 x 4, and we have (1 x 4) / (3 x 4) = 1/3, so 1/2 - 1/6 = 1/3.
What is the lowest common denominator for two-thirds and three-sixths?
6 the lowest common denominator is the least common multiple of the denominators after both fractions have been simplified as far as possible. 3/6 can be simplified as 1/2. 2/3 cannot be simplified any further. The LCM of 3 and 2 is 6, so the lowest common denominator is 6.
What is example of a common denominator and the lowest common denominator?
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.
What is the common denominator of 12 6 and 4?
There are infinitely many common denominators. The least of these is 12.
What is the lowest common factor of 3 and 4 and 6?
The lowest common multiple of 3,4, and 6 is 12. The lowest common factor is 1.

What is the lowest common denominator of 12 and 16?
The lowest common denominator of any two or more whole numbers, such as 12 and 16, will always be one (1) because 'common denominator' 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.If 12 and 16 are denominators, the LCD is 48If that's 1/2 and 1/6, the LCD is 6.

What are 3 common denominators of one third and one half?
6, 12, 18
How do you minus fractions?
First, you have to have a lowest common denominator. Eg: 1/2 - 6/13 The lowest common denominator is 26, because 13 * 2 is 26. You multiply 1/2 by 13, to make the denominator 26, which equals 13/26, then multiply 6/13 by 2 to get 12/26. So the equation with the lowest common denominators now plugged in is: 13/26 - 12/26 Subtract the numerators (13 and 12), so the answer is 1/26.
