Square root of a prime number in c

Now if "b" or "c" , any of them is greater than square root of "a "than multiplication of "b" & "c" will be greater than "a". So, "b" or "c" is always <= square root of "a" to prove the equation "a=b*c". Because of the above reason, when we test if a number is prime or not, we only check until square root of that number.
