There is none because 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 the numbers 5, 12 and 11 is 660.
660
The LCM of 378 and 660 is 41,580.
