Prime Numbers
A Natural number greater than 1 that is NOT a Product of two smaller Natural numbers. They only have 2 factors: 1 and themselves.
Prime numbers are a type of number that can only be divided evenly by 1 and itself. Examples of prime numbers include 2, 3, 5, 7, 11, and 13. One notable characteristic of prime numbers is that they can’t be formed by multiplying two smaller numbers together.
Some key properties of prime numbers include:
– Every integer greater than 1 can be expressed as a product of prime numbers. This is known as the Fundamental Theorem of Arithmetic.
– The number 2 is the only even prime number.
– There are infinitely many prime numbers.
– The prime factorization of a number is unique, meaning that there is only one way to express a number as a product of prime factors.
Prime numbers are useful in numerous mathematical applications, including cryptography, number theory, and computer science. They are also commonly used in various programming algorithms.
