Prime Number Which is Divisible By 1 And Number Itself

Example:2,3,5,7,11, Etc…..

In Prime We Should Have Only One Number

That’s Why it is Called Prime

Co Prime Number Which is Having A Common Factor Among Them

Example:21,22

21-Factors: 1,3,7,21

22 -Factors: 1,2,11,22

In Co -Prime We Should Have Two Numbers

In This We Have Only 1 Common Factor

That’s Why it is Called Co -Prime
