How is the square root of the key to the sieve of eratosthenes and finding prime numbers?
If you are trying to find a factor of a number n, then there is no need to search beyond s = sqrt(n). For if a factor of n is greater than s, then its factor pair will be less than s and so you should have found that already.For proof, let u be the factor pair. That is, t*u = n. Also s*s = n so that t*u = s*sDivide both sides by u*s so that t/s = s/uNow, t > s implies that t/s > 1 and so s/u > 1 which means that s > u.
Why do we test only the prime numbers less than the square root of the given number?
First, you do not. You must also test the square root of the given number. So the question should be in terms of "less than or equal to". Suppose you wish to test the number n and suppose s is the square root of n. Then s*s = n Now suppose p is factor of n, with factor pair q. so that n = p*q and, without loss of generality, assume that p ≤ q. Thus p*q = s*s so that p ≤ s ≤ q That is to say, one of the pair of factors of n will be less or equal to its square root while the other member of the factor pair will be greater or equal to the square root.

How do you know 4 is a factor of a number if eight is a factor?
Because 4 is a factor of 8. Any number that has 8 as a factor will also have 8's factors as factors.
