Best ResponseYou've already chosen the best response.0Well, there are lots of numbers that this will work for. If you take 5 and any multiple of 5 it will work.

Best ResponseYou've already chosen the best response.0It's kind of the opposite of multiples, but in order to find the greatest common factor, you use multiples.

Best ResponseYou've already chosen the best response.0Multiply a bunch of primes together. Then multiply a bunch of different primes together. Then multiply each of these badass numbers by five, and BAM you have two numbers whose GCF is 5. Make sure your primes are different though! With the exception that each is allowed to have a two, a three, or two twos.
