12 = 2x2x3 20 = 2x2x5 the both have 2x2 in common = 4

A common denominator of 20 and 30 is 600. This is NOT the least common denominator, though.

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.

A common denominator, though the least, is 260.

The highest common denominator is 12 because 12/12=1 and 24/12=2.
