22,but really it would depend on what other number your comparing it to and if you don't have a number to compare it then i do not know well I hope this helps. Ex; The GCF (greastest common factor) of 30 and 75 is fifteen, 15.
One only has one factor. If you have to, you can use (1,1)
Yes. One is a factor of everything.
Factor it once, and then factor the factors.

fifteen

15 is a factor of 60.The proof: 15 x 4=60(It is, of course, not a prime factor.)
The GCF is 1.
The GCF is 3.
