Every even number can be divided by 2 evenly
It means nothing at all. Every whole number, except 1, can be divided evenly by 1. Which leaves 1 which can be divided evenly by -1. Thus every whole number can be divided evenly by another whole number.
Odd numbers are numbers that cannot be divided evenly by 2. 253 cannot be divided evenly by 2 so it is an odd number.
These four numbers: 1 11 23 253.
