The highest or greatest common denominator of any two or more whole numbers, such as 81 and 48, 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 factors of 81 are 1, 3, 9, 27 and 81. For them to be common, they need to be compared to another set of factors.
common denominator of eight and nine
3
8100
Their product.
Since 8 is 23 and 81 is 34, the least common denominator is 23 x 34 = 648.

4536
It is: 324
The lcm or lcd is 5751
LCD(9, 16, 18, 81) = 1296

Convert both to decimal, and compare. For example, divide 81 / 105, and write down the decimal equivalent; the same for the other fraction. OR: Find a common denominator, and convert both to the common denominator. It need not be the least common denominator; any common denominator will do - for example, if you multiply 105 x 300, you have a common denominator (which is not the least common denominator in this case). The decimal method is much easier, by the way.
