Answer:
Step-by-step explanation: Natural number: Positive integers are called natural number like 1,2,3,4...
Whole numbers: Positive intergers including 0
Prime numbers: Numbers whose factors are only 1 and the number itself.
Composite* numbers: Numbers which have factors other than 1 and number itself
Co-prime number: Two natural numbers are co-prime if their HCF is one
Twin prime: Its a number that is either 2 less or 2 more than another prime number
Even number are numbers that ends with 0,2,4,6,8
Odd numbers are numbers that end with 1,3,5,7,9
Explanation:
When two numbers (they may not be prime) do not have any common factor other than one between them they are called co-prime or relatively prime.
It is obvious that two prime numbers are always co-prime. For example, 17 and 23.
However, even two composite numbers can also be co-prime or relatively prime. For example 16and 25 do not have any common factor other than one. Similarly 84 and 65 do not have any common factor and are hence co-prime.
