Webb27 apr. 2011 · Suppose n is not a prime number (greater than 1). So there are numbers a and b such that n = ab (1 < a <= b < n) By multiplying the relation a<=b by a and b we get: a^2 <= ab ab <= b^2 Therefore: (note that n=ab) a^2 <= n <= b^2 Hence: (Note that a and b are positive) a <= sqrt (n) <= b WebbThe 1,000 smallest prime numbers 2 3 5 7 ...
