The least common denominator is 60.

The LCM of 3, 6, and 12 is 12.The least common denominator is the same as the least common multiple.The least common denominator is the smallest multiple divisible by 3, 6, and 12. Since 12 is divisible by 3, 6, and 12, and the smallest multiple of 12 is 12 x 1 = 12, that is the least common denominator or least common multiple.

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions. Even if you converted your numbers (x) to their fraction equivalents (x/1), the LCD will always be 1.

A common denominator, though not the least one, is 12*20 = 240.
