Question

what is the unique number​

Answer 1

$\huge\star\underline\mathfrak\red{Answer:-}$

1 is called a unique number because it is neither a prime number nor a composite number. It has only one factor, i.e, the number itself; and to be a composite number also the number must have two factors, i.e, 1 and the number; and a prime number also must have more than two factors.
