Yes 1 is a factor of every number except 0.
This is literally true but incomplete. The number 1 is a factor of any number and can be that factor an infinite number of times. Most people don't like infinity. It causes many problems. That's (partially) why 1 is not considered a Prime number although it has no factors other than itself and 1 (yes, redundant to infinity).
So when someone asks for prime factors of a number, be sure to not include 1. Unless you are an infinite entity and infinite time to write out the prime factors.
