Prime Numbers from 1 to 100 Let’s learn how to find prime numbers from 1 to 100 We follow the steps Cross out 1 as it is neither prime, nor composite 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 is prime as its factors are 1 & 3. So, all its multiples will have 3 as factor. So, cross all those numbers. Numbers like 3, 6, 9, 12, 15, 18, … will be crossed out 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
