Question

Why is 1 an unique number?​

Answer 1

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.

Answer 2

Answer:

Bcz ifs we devide any number bye itself it's gives us 1 and ifs we multiple any number bye 1 we will get the same number

For example

$6267420977 \div 6267420977$

= 1

$6267420977 \times 1$

=6267420977
