WebApr 9, 2024 · Step 1: First we write all the natural numbers row-wise and column-wise like the given table. Step 2: Cross the number 1 as it is not a prime or composite number. Step 3: Now leave 2 and cross the multiples of 2 as all are composite numbers. Step 4: Next leave 3 and cross the multiples of 3 as all are composite numbers. WebWe will use Eratosthenes’ sieve to discover the prime numbers between 1 and 100. Using the grid, it is clear that 1 is not a prime number, since its only factor is 1. The first prime number—and the only even prime number—is 2. Since all other even numbers are divisible by 2, they cannot be primes, so all other prime numbers must be odd. time soldiers arcade game
