Add one to the greatest number you can think of. The answer is either or neither. Whole numbers don't stop.
Odd and a multiple of three- 999
Some confusion as to whether it is "I" or "you". The number in question is 8642
A prime number is any number that only has one and itself as factors. By definition even numbers have a factor of two. Therefore the greatest and only even number that is prime is the number 2.
The square of every positive or negative even whole number is a positive even whole number. The square of every positive or negative odd whole number is a positive odd whole number. There are an infinite number of each kind.

There is no such number. If N were the greatest even number then N+2 would be a greater even number. So N could not be the greatest even number.
It does not exist.Proof: Indeed, suppose that this number exists, and denote it by X.Then X+1 is also a whole number (by definition of the whole numbers). So X cannot be the greatest number since X+1 is even greater, which contradicts the assumption of the first line. The same argument follows for X+1 (compared to X+2), and so on.Consequently, there is not a greatest whole number.Remark: One may consider that infinite is the greatest whole number (without such an above contradiction, since infinite+1=infinite), however infinite is not defined to be a whole number.

The greatest 2-digit even number is 98
No. Because both numbers are even, they each have 2 as a factor. Even if they have a larger factor in common, it will be a multiple of 2, so the greatest common factor will be an even number.Yes. Two even numbers are each divisible by 2. The GCF must therefore always have two as one of its factors; this makes it even.
Look at the last digit. If it is even, the whole number is even. If it is odd, the whole number is odd.

If the last digit is an even number, the whole number is an even number.
Never.
256 is the greatest even square number that is less than 300.
