Is the number one a prime number?

Answer   Submitted by Answiki on 06/08/2022 at 06:20:38 PM UTC

One is not a prime number.


A prime number has exactly two divisors (1 and itself). In the case of the number 1, the two divisors, 1 and itself, are not distinct: they are the same. So the number one does not meet the definition of a prime number.
