The Greatest Common Factor (GCF) of some numbers, is the largest number that divides evenly into all of the numbers. Like, the GCF of 10,15, and 25 is 5. so for 5 and -3 your The Greatest Common Factor (GCF) of the numbers 5,-3 is 1 because 1 is the greatest number that divides evenly into all of them.

http://www.webmath.com/intgcf.html is a very helpful website for finding GCF

Thank you! I'm already a fan of you!

thank you so much!!

hey, do you know how to factor polynomials?
anonymous
  • anonymous
Uhm do you have an example?
anonymous
  • anonymous
yes one of them states.. (2a+ab)+(2c+bc)
anonymous
  • anonymous
First Question: Does your polynomial have a GCF? Always factor out the GCF first (when there is one)!
anonymous
  • anonymous
yes but i don't know it
anonymous
  • anonymous
it's 1
anonymous
  • anonymous
ok one sec let me look at this again give me just a sec
radar
  • radar
They have already grouped it so there is a common factor within each grouping
anonymous
  • anonymous
correct?!
anonymous
  • anonymous
(2a+ab)+(2c+bc) 2a+ab+(2c+bc) (b+2)(c+a)
anonymous
  • anonymous
the two bottom answers must match ^^
anonymous
  • anonymous
WHat do you mean the two bottom answers must match? (b+2)(c+a) would be the final answer I think
anonymous
  • anonymous
like the answer would be (the final would be ) (1r+4)(2b-8)

Here is the problem as you stated: (2a+ab)+(2c+bc) Look closely at the first part in paren. The 2a+ab.........What do you see that is common to both terms?
anonymous
  • anonymous
it has an a
radar
  • radar
Yes, remove the a and express it like this a(2+b). Do you agree that is the same thing?
anonymous
  • anonymous
ohhh ok i see it
anonymous
  • anonymous
thank u
radar
  • radar
Good now the second part, what do you see that is common to both terms in the second set of paren namely the (2c+bc)?
radar
  • radar
Big_rod when you return...... that can be factored also, extracting the c getting c(2+b) now write the equation like this using the revised a(2+b)+c(2+b) Now hat do you see that is common to both terms? The (2+b) is common, extract that and get the final answer , the same one that mmbuckroos got (2+b)(a+c)

Thanks Radar you explained that much better than I did! Good review for me as well thanks!
