You need at least two numbers to find a GCF.
The GCF of 91 and 393 is 1.
There can be no greatest common multiple. If x were the greatest common multiple, then 2x would be a still greater common multiple. So x could not be the greatest. Thus there is no such thing as a greatest common multiple.
You need two numbers to compare in order to find a least common multiple.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple is infinitely large, the least common multiple is 1365, the greatest common factor is 1.
Oh, dude, the greatest common multiple of 4, 5, and 3 is just the largest number that all of them can divide evenly into. So, you just gotta look at their multiples and find the biggest one they all share. It's like a math puzzle, but not as fun as a jigsaw puzzle, you know?
There can never be a greatest common multiple. If a number, X, is claimed as the greatest common multiple, the 2X is a common multiple, and it is greater than X which contradicts X being the greatest.
There is no greatest common multiple - whatever common multiple you come up with as the greatest one I can add their lowest common multiple (45162) and get an even higher multiple. There is a greatest common factor, which for 3474 and 26 is 2.
The greatest common multiple is infinite.
The greatest common multiple of any set of integers is infinite.
