There are 1000 lockers. There are 1000 students. Every student opens their locker according to the multiples of their student number. FOr example: Student 1 opens every locker that is a multiple of 1. Student 2 opens every locker that is a multiple of 2. Student 3 opens every locker that is a multiple of 3 and so on. If the locker is already open, then it gets closed. Please give me the awnser and how you got it. PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

squared numbers are open
1^2, 2^2, 3^2, ....
every other number has even factors when a number is a square of something, it has odd factors
1 - open 1*1
2-closed 1*2
3-closed 1*3
4-open 1,2,4
5-closed 1,5
6-closed
7-closed
8-closed
9-open
10-closed
16-open 1,2,4,8,16
number squared is in the middle > odd factors

This isn't that hard, just time taking. Find how many multiples ther are of each number.
If lockers start closed.....
Odd number of multiples = open locker
Even number of multiples = closed locker
1= 1 multiple = odd = opened locker
2= 2 multiples = even = closed locker
10 =3 multiples = odd = opened locker
Get it. just find the amount of multiples in each number then find if it is an odd or even number. Easy, just time taking.

What is the question that you are asking? I never heard of that infamous problem so I don't know what the issue is. So what if students can open more than one locker? Is that the problem?

this website, in conjunction with poncho Rio's answer, should save you a fair bit of time. (beware, last time I checked the 350-400 link was whacked, but you can still get to all of them)
