There is no such number. Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be higher than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a highestmultiple.

Can the GCFof 12 and 30 be greater than 12?

No. All factors of a number are less than or equal to it. Therefore the highest factor of 12 is 12. The common factor of 12 with any other number (greater than) 12 cannot be greater than the highest factor of 12 which is 12. Thus no. [The hcf(12, 30) = 6.]
