What are the Prime Numbers 1-100

A prime number is a subset of the set of natural numbers, which is greater than one, and it has only two positive divisors, that is, 1 and the number itself. If any number doesn’t satisfy this condition, then it can be called a composite number. It means any natural number, which is greater than one and which have positive divisors other than 1 and the number itself called composite numbers. There is infinite number of prime numbers present. Here we discussed the prime numbers up to 100.

There is no specific pattern for finding all the prime numbers, but from early times a specific method has been followed called the Sieve of Eratosthenes. Lets see how this method is worked out using numbers from 1 to 100.

First of all, all the numbers from 1 to 100 is written down

 1    2    3    4    5    6    7    8    9    10    11    12    13    14    15    16    17    18    19    20    21    22    23    24    25

26    27    28    29    30  31     32    33    34    35   36    37    38    39    40   41     42     43     44      45    46    47   

48    49   50    51  52    53   54    55    56   57    58    59   60   61    62   63   64    65    66    67   68   69     70  

71   72    73      74     75    76   77    78   79    80    81    82    83    84    85    86  87    88    89   90    91    92   93   

94   95    96    97   98    99   100

Step 1: Ignore the number 1.

Step 2: Start with 2. Except 2, remove all the multiples of 2.

Step 3: Next move to 3, except 3, remove all the multiples of 3.

Step 4: Repeat this process till the end

Step 5: The list of prime numbers from 1 to 100 are

2  3   5   7   11   13   15   17   19   23   29   31   37   41   43   47   53   59   61   67   71   73   79   83    89    97

This list can help you the identify the prime numbers up to 100 easily.
