Question?

Posted 18 September 2007 - 11:06 AM

Hey I was wondering, if I have the numbers 0 and 11 wouldn't the Greatest Common Factor be 11? My reasoning is that you can do 0x11 and get 0 and you can do 11x1 and get 11. Therefore 11 is the GCF, right? If anyone could verify or deny my question that would be great.

mastergeek666, this is about the fourth or fifth time you have asked a question in the lounge that was in some way programming or site related. this has gotta stop now. as a mastergeek you should know enough to read and place questions in a forum at least slightly more suitable to your question. next time you do this you'll lose posting privileges for 24 hours. if you have any further questions on the matter, pm me. i'll move your topic to something more suitable.

Also, you already have a GCF topic going in another forum. Why can't you just ask your question in that thread? This is the second time I've asked you not to create new topics for something related to another topic you have going.

My apologies, I'll try to keep track of all the post's I do so as to better organize rather than just post like crazy.

Re: Question?

although it is true, 0 and 11 are both divisible by 11, the fact of the matter is, that is accepted that 1 is the only number which properly divides 0, as all numbers have a secret denominator of 1.

if what you say about 11 being the highest common factor were true, then:
0/1 = 0/11 = 0/infinity = 0, thus a factor
11/1 = 11, 11/11 = 1, 11/infinity = 0, thus a factor? no, this scalability does not work.

technically 0 has no factors, but for complexities sake, 1 is the only factor.

I think GCF is usually applied to natural numbers only i.e. 1 onwards...

i think you are right Louisda16th, but i still like my attempt at a proof by contradiction :) it's practice for my algorithm analysis course.

Proof by contradction-yeah rocking method.
Algorithm analysis- sounds interesting. Do you have any online articles/ tuts on this. Im interested in learning cryptography, seganography and AI :)!

not yet, but it is a very interesting topic, very math oriented (algebra, etc) perhaps once i finish the class i will attempt1 or 2. I have done mass amounts of cryptography, and i even have a class on cryptography next semester, i am really looking forward to it :)

Possibly you could write some tuts as well? :). We've got only cryptography in our engineering course in the 5th or 6th sem.
