Why is 1 not a prime nor a composite number?



1 not a Prime nor Composite Number


Prime Numbers:
  • Prime numbers are numbers that are greater than 1 and have only two factors - 1 and the number itself.
  • Since 1 has only one factor (itself), it does not meet the definition of a prime number.




Composite Numbers:
  • Composite numbers are numbers that have more than two factors, including 1 and the number itself.
  • 1 only has one factor (itself), so it does not fit the definition of a composite number either.




Unique Nature of 1:
  • 1 is a unique number that is neither prime nor composite.
  • It stands alone as a unit and does not fit into the categories of prime or composite numbers.
