It is the first and smallest positive integer of the infinite sequence of natural numbers. It is the smallest positive integer, and smallest natural number 1 is the multiplicative identity, i.e Any number multiplied by 1 equals itself, for example A ⋅ 1 = a {\displaystyle a \cdot 1=a} and 1 × a = a {\displaystyle 1\times. Is 1 a prime number
