Answer:
No, it is not a prime number. And even composite number.
Step-by-step explanation:
Why is 1 not a Prime Number?
The answer to this lies in the definition of prime numbers itself. For a number to be called as a prime number, it must have only two positive factors. Now, for 1, the number of positive divisors or factors is only one i.e. 1 itself. So, number one is not a prime number.
But, Why is 1 Not a Composite Number?
The answer to this also lies in the definition of composite numbers. According to the definition, a composite number is a natural number which more than two positive factors. But, 1 has only 1 factor i.e. 1 itself. So, one is not a composite number.
