The common denominator of any two or more whole numbers, such as 6 8 and 9, 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.

The LCD or LCM is 504
common denominator of eight and nine
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.
I am assuming you mean 8/9ths 4/6ths or 1/3rd if that is the case, 1/3rd is the smallest, followed by 4/6ths and then 8/9ths. First convert to common denominator, which is 9. 8/9 = 8/9 4/6 = 6/9 1/3 = 3/9 Now compare the numerators in the common denominator fractions. The common denominator fraction with the smallest numerator is the smallest. The smallest is 3/9; so 1/3 is the smallest fraction.
