Introduction to prime numbers 1-100:
Prime numbers are the numbers it can be divided only by 1 and the number itself.Prime numbers cannot have any thing or factors except one and the number by itself. The +ve(positive) integers are divided into two such as prime numbers and composite integers.Totally there is 25 prime numbers between 1 and 100. So remaining are the composite numbers.
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 are 25 prime numbers between 1 to 100.That twenty five prime numbers are in between 1-100 These numbers cannot be divide by any other number except 1 and the number itself.And the same is called prime numbers.
The prime numbers from 1-100
In the prime number composite numbers have thing or factors compare than other is one and itself Except the 25 prime numbers between 1 to 100 all the other numbers are composite numbers.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.
Problems of prime numbers between 1-100
solving prime numbers 1-100:
Here we mentioned the prime numbers from 1 to 100 only
So many prime numbers are there.
Let us see some examples,
Example 1:
To determine the given number is prime or not :one hundred forty-three ?
The factors of 143 are 1, 11, 13,143
So here we have factors for 143 other than 1 and 143
So this is not a prime number
The remaining prime number compare than other numbers are called composite number
So 143 is a composite number
Example 2:
To determine the one hundred thirty-one is prime or not?
Solution
The factors of 131 is 1, 131
So here we don’t have any other factor except 1 and the number 131
So the number 131 is a prime number
Example 3
To determine the prime numbers between thirty to thirty-five?
Solution
30 - Factors - 1,2,3,5,6,10,15,30 – Not a prime number
31 – Factors – 1,31 – Prime number
32 – Factors – 1,2,,4,8,16,32 –Not a prime number
33 - Factors - 1,3,11,33 - Not a prime number
34 - Factors - 1,2,,17,34 – Not a prime number
35 - Factors – 1,5,7,35 –Not a prime number
So from 30 to 35 we have only one prime number
31 is only prime between 30 to 35

So the number 131 is a prime number
Example 3
To determine the prime numbers between thirty to thirty-five?
Solution
30 - Factors - 1,2,3,5,6,10,15,30 – Not a prime number
31 – Factors – 1,31 – Prime number
32 – Factors – 1,2,,4,8,16,32 –Not a prime number
33 - Factors - 1,3,11,33 - Not a prime number
34 - Factors - 1,2,,17,34 – Not a prime number
35 - Factors – 1,5,7,35 –Not a prime number
So from 30 to 35 we have only one prime number
31 is only prime between 30 to 35
