Some remote controls require two batteries, some require three batteries, and some require four. A manufacturer wants to please every battery buyer. How many batteries should be put in each pack that is sold?

12, for backup, obviously!

well its actually not obvious. How did you get 12, or did u just make it up?

LCD of 3 and 4

Maybe I am overthinking this problem but why couldnt you just add three numbers together and get 9? By having 9 batteries wouldnt it cover all three of the multiples? (2pack, 3pack, 4 pack)

The 2 and 4 would have one left over

Sorry, I think u are on the right track, but I am not full understanding what you are saying. U are not using full sentences so I just am getting like half the explanation. Would u mind clarifying what you meant by your last statement. Thanks \

I will give u some batteries if u do

If anyone else wouldnt mind helping with this problem I would appreciate it, and please dont just say a random number if you wouldnt mind briefly explaining how you got it. Unlike some people

it's 12 because then a remote that uses 2 batteries will be ok for 6 lots of usage
a remote that uses 3 will have 4 lots of usage
a remote that uses 4 will have 3 lots of usage

You are looking for the smallest number that 2,3 and 4 go into ... then there will be no batteries left over (when the remotes run out (again and again)

Thank u so much, that makes complete sense. Thanks for the help.
