Of times: urongwa unsolved zvakavanzika

Prime nhamba tiri rimwe zvinofadza zvikuru kwemasvomhu chakajairika anenge Akakwezva masayendisiti uye vagari kweanodarika zviviri zvamakore. Pasinei zvino tiri kurarama munguva makombiyuta uye zvemberi mashoko zvirongwa, zvakavanzika zvizhinji inonyanya nhamba haina kugadzirisa kusvikira ikozvino, pane kunyange vamwe masayendisiti havazivi sei kutaura.

Of times - ichi chinozivikanwa asi pamusoro chepuraimari svomhu Chokwadi, vaya dzinongoitika nhamba ayo akakamurwa pasina chasara chete nomunhu uye pachayo. Panzira, kana munhu wechisikigo nhamba iri divisible, kunze apa, zvimwe chero nhamba, kunonzi nezvakawanda. Imwe yakakurumbira theorem no rinoti rinoumba chero nhamba inogona achimiririrwa chete zvinoita zvinobva of times.

A shoma dzinonakidza chokwadi. Chekutanga, kuti chikwata chakasiyana mupfungwa kuti, chaizvoizvo, hahusi nyore kana kumiririra nhamba. Panguva iyoyowo, masayendisiti achiri dzakasarudza anokukonzera kuti boka rokutanga zvakananga, sezvo pamutemo kwazvo zvinogutsa zvawaitaura.

Chechipiri, chete kunyange nhamba, wormed boka "of times" ndizvo zvoga deuce. Zvimwe kunyange nhamba kuti pano nyore asingagoni, nokuti, nokuda tsanangudzo, kuwedzera pachangu uye chikwata inokamukana munyika mbiri.

Prime nhamba, pakarongwa iyo, sezvataurwa pamusoro apa, zvinokwanisika kutanga chete, vanomirira isingaperi dzino akadai magumo, sezvinoita nhamba rwokuzvarwa nhamba. Zvichienderana chinokosha theorem no kuti svomhu, tinogona kugumisa kuti of times kumbobvira hwakakanganiswa, uye hwokusingaperi, nekuti zvimwe vanongoerekana vave yakapindira uwandu zvakanaka integers.

Simple nhamba haamo mune zvakasikwa nhamba randomly, zvingaita sezvinoshamisa pakutanga kuaona. Vanyatsofunga navo, tinogona wangoona mashoma features, kupfuura inonakidza zvacho pamwe vainzi chislami- "pemapatya." Dana navo saka nokuti vamwe isinganzwisisiki nzira vakanga inotevera musuo nepedyo, akaparadzaniswa chete kunyange-delimiter (shanu, nomwe, gumi nemapfumbamwe).

Kana isu kunyatsoongorora navo, tinogona kuona kuti mubatanidzwa nhamba idzi anogara vakawanda zvitatu. Uyezve, kana yakakamurwa zvitatu vamwe vakasara vakasara iri nguva dzose mbiri, uye kodzero - a chimwe. Uyezve, kuparadzira rwevanodzvinyirira zvepanyama munhevedzano nhamba zvinogona zvafanotaurwa, kana chipo siyana iri yose vibrational sinusoids huru iyo vari inoumbwa kupatsanura nhamba nhatu uye vaviri.

Of times havasi chete pasi kuvhara kuongororwa kubudikidza mathematicians enyika, asi haana refu uye zvinobudirira kushandiswa kwegadziriro siyana mitsara nhamba, kutorwa, Inter Alia, nokuti shifrografii. Zvinofanira kuzivikanwa kuti akawandisa Puzzles chokuita izvi zvinoshamisa okunze, vakamirira kutibatsira dzavo, mibvunzo yakawanda havasi chete kwouzivi asi rinoshanda kukosha.
