Question

What is the smallest prime number?

Answer 1

The definition of a prime number is a number that is divisible by only one and itself. A prime number can't be divided by zero, because numbers divided by zero are undefined. The smallest prime number is 2, which is also the only even prime.

Answer 2

Remember - '1' is a number which is neither prime nor composite .

So , If we will count from 0 and we will exclude '1' , we will get the next number '2' . 

According to the above theory , 2 is the Smallest Prime number .

Hence , The smallest prime number is 2 .
