## Which is the smallest whole number?

0Solution. Zero (0) is the smallest whole number.

## What is the fastest way to find a prime number?

To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can’t be a prime number. If you don’t get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number (see table below).

## How many prime numbers are there between 1 and 100000?

## Why 1 is not a prime number?

The confusion begins with this definition a person might give of “prime”: a prime number is a positive whole number that is only divisible by 1 and itself. The number 1 is divisible by 1, and it’s divisible by itself. But itself and 1 are not two distinct factors. … Excluding 1 from the primes smooths that out.

## Which is the largest prime number?
