 | | One is currently not usually thought of as a prime number, but it is considered by some to be such, and it would be under a simple definition for primality: that the number be only divisible by one and itself - one is certainly itself. |
 | | To exclude the number one from the list of prime numbers, primality is defined as a number having exactly two distinct divisors, one and itself, itself being a number other than one. |
 | | In mathematics, one is perhaps the number that most often appears as a literal constant in axiomatic equations, but in a way, it appears in all equations as an implicit multiplicand, due to multiplicative identity. |
