You have to break 1260 down into it's number tree. Start by dividing the number by 2 until you can't do it evenly, then divide by 3, and so on until no more divisions can be made: 1260/2 = 630 So we have one prime factor, 2 and are left with 630: 630/2 = 315 Now we ...

In either case though, you have to think. How many even or odd numbers are there between 1-100? The answer is 50. So in order to guarantee the removal of an even number 51 integers must be randomly removed.

You may have to clarify, do you mean how many times will this have to be done to guarantee the removal of an even or odd integer? Because just removing one integer guarantees the removal of an integer.
