Whm>y m> do we check up to the square root of a prime number to determine if it is prime?

If a number n is not a prime, it can be factored into two factors a m>and m> b:
n = a * b
Now a m>and m> b can't be both greater than the square root of n, since then the product a * b would be greater than sqrt(n) * sqrt(n) = n. So in anm>y m> factorization of n, at least one of the factors must be smal...
