No.
No.
Yes, if it is a multiple of the other one.
The least common factor of any set of integers is 1. The least common multiple can never be smaller than the larger of the two starting numbers.
There is NO greatest common multiple because I can always add another lowest common multiple and get an ever greater number that is a common multiple.
The LCM is 396. The next common multiple is 792.
No, the highest common multiple is an infinite amount.
Oh, dude, the least common multiple of 3, 7, and 8 is 168. Yeah, it's like the smallest number that all three of those numbers can divide into evenly. So, if you're ever throwing a party with 3, 7, and 8 guests, you'll know when to bring out the party favors.
It will go on for ever.
I don't know that they ever did. The least common factor of any set of integers is 1. The greatest common multiple of any set of integers is infinite. Values that are the same for every set of numbers are useless for differentiating between them.
There is no greatest common multiple. Ever! If x were the greatest common multiple, then what about 2x? Since x is a multiple of 16 and 24 then so also is 2x, so that 2x is a COMMON multiple. And it would certainly be greater that x. So 2x is a common multiple that is greater than the greatest common multiple. What?!
The highest is infinity, because numbers go on for ever. The highest common factor is 6 and lowest common multiple is 60.
A common occupation of historians and archaeologists is finding out about the past.
