To simplify matters.
ex... 15 x 23
since 15 is 3 x 5 we can sub.
15 x 23 = (3x5) x 23
= (3) x (5 x 23)
= 3 x 115 easier to multiply by 5 than 15
= 345

No, all even numbers share one factor. The one factor being 2.
what word can I substitute for constitutes
unanimous
The word could be fragile, or possible flimsy.
There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
all of them.
No because every single number has a factor of one, therefore you have one as the common factor.
One such factor pair is 10 and 80.
100 and 1.01 is one possible answer.
Possible examples are assistant, acolyte, adjutant, and aide-de-camp.
One is a factor of all nonzero numbers.
Yes. Not counting one as a factor, you could have numbers like 6 and 10 which only share one common factor, 2.
