From the above diagram, we can see that for even numbers, the diagram is complete and for odd numbers there is 1 box less. Even numbers can be divided into two groups. For example four can be divided into two groups of two.(

So even numbers start with 0 and odd numbers start with 1.

So in general we can say that the numbers that ends with above digits are even numbers.

The number whose unit digit is other than 0,2,4,6,8 are odd numbers.

The smallest even natural number is 2 and smallest odd natural number is 1.
