List of prime numbers

Introduction:
Prime numbers are the numbers which can be divided only by 1 and the number itself. Prime numbers cannot have any other factors except one and the number by itself. The +ve(positive) integers are divided into two such as prime numbers and composite integers rules.
Totally there is 25 prime numbers between 1 and 100. So remaining are the composite numbers. Now we give the list of prime numbers upto 100.
The numbers are like
2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97
as the list shows there are 25 prime numbers between 1 to 100.
That twenty five prime numbers are in between 1-100, These numbers cannot be divided by any other number except 1 and the number itself. And the same is called prime numbers and includes the list of prime numbers.

List of Non Prime Numbers from:

Among natural numbers, composite numbers have other factors compared to prime numbers other than one and itself except the 25 prime numbers between 1 to 100 all the other numbers are composite numbers. All the numbers except the numbers in the list of prime numbers upto 100 are composite.
In that, the list of composite numbers 4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30,32,33,34,35,36,38,39,40,42,44,45,46,48,49,50,51,52,54,55,56,57,58,60,
62,63,64,65,66,68,69,70,72,74,75,76,77,78,80,81,82,84,85,86,87,88,90,91,92,93,94,95,96,98,99,100.......
These were the composite numbers between 1 to 100.
