Answer 2

Answer:

Step-by-step explanation:

Prime numbers are those which have only 2 factors - first is the number itself and another is 1 ..

this definition might look confusing but believe me its really easy ..

Lemme make u understamd with an example ..

2,3,5,7,11... r some of the prime numbers ..

Look at 2 ..

The only factors of 2 are 1 and 2 ..simply it just means that 2 comes in the table of 1 and itself that is 2 .. now look at 5 .. it comes in the table of 1 and table of 5(itself ) ... so only 2 factors are there (i.e) 1 and the number itself ...

Now composite numbers are those which have more than 2 factors .. this simply means the numbers which comes in more than two tables .. for instance 10 is a composite number .. it comes in more than 2 tables :-

In the table of 1 , of 2 , of 5 , and of itself (10 ) ...other examples of composite numbers are 4,6,9,8.... and so on..

and WE DO THE PRIME FACTORISATION OF COMPOSITE NUMBERS TO FIND THE PRIME NUMBERS OF WHICH THEY ARE PRODUCT ....
