 Hi and welcome to the session. Today we will learn about prime and composite numbers. So first of all let us see what are prime numbers? Numbers within one whose only factors are one, number itself, two numbers. Now let's see what are composite numbers? For example numbers like 4, 6, 8, 9, 10 etc are all composite numbers. Now we know that one is not a prime number and has only one factor which is one itself. So it is not a composite number also. That means we have one is neither. Now let's see what are even or all even numbers as they are the multiples of two odd numbers, multiples of odd numbers as they are not the multiples of two. If you have a very large number like they are fine even in odd numbers then you can use one result. We have 8 at one's place starting from 2. So from here the smallest prime number. We have understood all the concepts. Goodbye, take care and keep smiling.
