What is the smallest prime number between 1 to 20?

2 is the smallest prime number between 1 an d 20.

Why is 2 the lowest prime number?

(But it is not at all based on “being too small.” See Graham’s number.) Proof: The definition of a prime number is a positive integer that has exactly two distinct divisors. Since the divisors of 2 are 1 and 2, there are exactly two distinct divisors, so 2 is prime.

Why 0 and 1 is not a prime number?

In fact, all positive integers are divisors of 0. 0. It is not a positive integer and does not satisfy the fundermental theorem of arithmetic(you can’t write it as the product of primes;0 is not prime) and it doesn’t divide by itself. In conclusion, 0 is like 1 in the fact that it is neither prime nor composite.
