    Math Question ? ? ?
    hi, i was hoping someone could help me. I'd like to know how and or the formula to find out where two numbers will meet. say for example you start with 7 and keep adding 7, and say you also start with 9 and keep adding 9. How do you figure out(using a formula when and where the 2 numbers meet the same total. such as this example would be 56, but i would like to know how to do this using more difficult numbers. also what branch of math would this be? any and all help is appreciated, and thank you for your help. . . .Suzy

        Well Suzy, you add 7+9 because everytime u add a 7 u also gotta add a 9. so 7+9=16 right? and 56/16 = howmany times ull need and in this case, FOURRR

          Say a more complicated... 8 and 9 to form 357. So we add 8 and 9 xxx 8+9=17 Then we do 357/17 by calculator and we get 21!!

          Hope this helps
          p.s. im a college kid in pure science lawl... school's starting tmr..

              What you're trying to do is find the least common multiple. There are several different methods that you can employ to find it, including prime factorization and Euclid's algorithm, both of which are well documented on the web.

                The least common multiple of the two numbers is the total where they first meet. So for your example the answer is 63.

                    I'm confused. How many times does nine go into fifty-six? Also, how is 56/16=4?
