Let’s learn how to find prime numbers from 1 to 100

 

Prime Numbers from 1 to 100 - Prime numbers from 1 to 100

 

We follow the steps

  1. Cross out 1 as it is neither prime, nor composite

  2. 2 is prime as its factors are 1 & 2.
    So, all its multiples will have 2 as factor. So, cross all those numbers.
    Numbers like 4, 6, 8, 10, 12, 14, … will be crossed out

  3. 3 is prime as its factors are 1 & 3
    So, all its multiples will have 3 as factor. So, cross all those numbers.
    Numbers like 6, 9, 12, 15, 18, 21, 24, .... will be crossed out

  4. Repeat the process for other numbers until we find all the prime numbers

 

Thus, Prime numbers from 1 to 100 are

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
