Prime numbers are numbers greater than 1 that only have two factors, 1 and the number itself. This means that a prime number is only divisible by 1 and itself. If you divide a prime number by a number other than 1 and itself, you will get a non-zero remainder.
First Ten Prime Numbers
The first ten primes are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.
Properties of Prime Numbers:
- Prime numbers are natural numbers greater than 1.
- 2 is the smallest prime number.
- 2 is the only even prime number. All the prime numbers except 2 are odd.
- Any two prime numbers are always coprime.
- Any composite number can be uniquely expressed as the product of its prime factors.
- A prime number has only two factors -1 and the number itself.
- If two prime numbers have only 1 composite number between them, they are called twin-prime numbers.
- Every even positive integer greater than 2 can be written as the sum of two prime numbers.
- Every positive integer greater than 1 has at least one prime factor.
