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, is 1680.
A common denominator, though not the least one, is 16*24 = 384.

LCD(24, 6) = 24.
A common denominator, though not the least one, is 6*4 = 24.
The least common denominator (LCD) is 1.
The least common denominator is 2 * * * * * That is totally wrong. LCD(24, 36) = 72
A common denominator, though not the least, is 1680.
A common denominator, though not the least, is 240.
It is: 24
A common denominator, though not the least one, is 16*24 = 384.
A common denominator, though not the least one, is 24*21 = 504.
