Prime numbers and Composite numbers
The numbers which are exactly divisible by a number except 1 and the same number are termed as composite numbers.
Example: 4 is a composite number since it is exactly divisible by 2 other than 1 and 4. Set of prime numbers with composite numbers and 1 forms the set of positive integers.Students can learn more about the Prime numbers by observing the examples of Prime numbers.
Prime number theorem states that if we select a random number nearby some larger number N, the chance of the random number to be prime is 1/ln N. ln N represents natural logarithm of N. Below are few facts of prime numbers which will help you to get math answers:
2 is the only even prime number as all other even numbers are divided by 2.
Zero and 1 are not considered as prime numbers
If the sum of a number's digits is a multiple of 3, that number can be divided by 3.
