This cannot be answered properly because at least two numbers are required.
The common denominator of any two or more whole numbers will always be 1.
There is none because the Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.
The least common multiple of 43 , 6 = 258
The least common multiple of 43 , 40 = 1,720
The least common multiple of 43 , 44 is 1,892
The least common multiple of 43 , 6 = 258
The least common multiple of 43 , 41 = 1,763
The least common multiple of the numbers 42 and 43 is 1,806.
The Least Common Multiple (LCM) for 22 43 is 946.
Least Common Multiple (LCM) for 45 43 is 1,935
The least common multiple of the numbers 7 and 43 is 301.
