Multiply them together. The GCF is 66.
Since they are all prime numbers, their LCM is the product of all three of them.
The Least Common Multiple (LCM) of (54,63) is 378.
24.

It is: 6
The way to solve this is as follows:Find the least common multiple of the two numbers.Multiply this least common multiple by 2 and by 3, to get the next two common multiples.
it's three.
These do exist.
