|Zero and one are not prime numbers.||0, 1, and 3 are not composite numbers|
|only two even prime numbers||The first composite number is 4|
|Examples of prime numbers are 2, 3, 5, 7, 11, 13, etc||Examples of composite numbers are 4, 6, 8, 9, 10, etc.|
Prime Numbers and Co-prime Numbers
|prime numbers||co-prime number|
|Prime numbers are divisible only by 1 and by themselves; they are not divisible by any other number.||Such numbers or such pairs which are divisible by only one or have common factor 1, then that number is called co-prime number.|
|Must not be divided by an additional number||The common factor should be 1|
|It has two factors||Numbers must be in pairs|
