Webcalled a prime number. By the way we will use the letter proutinely to denote a prime number. Example 1.2. 101 is a prime number. Proof. How to prove this? Well obviously one only needs to check for divisors dwith 1 <100. Moreover if dis a divisor, then there is an eso that de= 101, and one of d, eis ≤ √ 101 so we only need to check out ... WebOne part of algorithmic number theory is finding efficient methods (“algorithms”) for computing things whose existence is promised by number theory, like large primes and their two-squares decompositions. Another part is computing data for number-theoretical problems for which we do not have theorems yet, in order to surmise patterns that ...
