Understanding Prime & Composite Numbers
What are Prime Numbers?
Prime numbers are natural numbers greater than 1 that have exactly two distinct positive divisors: 1 and the number itself. Examples: 2, 3, 5, 7, 11, 13, etc.
What are Composite Numbers?
Composite numbers are natural numbers greater than 1 that are not prime. They have at least one divisor other than 1 and themselves. Examples: 4, 6, 8, 9, 10, etc.
Special Cases
The number 1 is neither prime nor composite. The number 2 is the only even prime number. All other even numbers greater than 2 are composite.
