Why on Earth is 1 not considered as a prime number????? ​

Answer 1

Answer:

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.
