Primes: chizolowezi sanathetsedwe zinsinsi

manambala Yaikulu ndinu mmodzi wa chidwi kwambiri masamu chodabwitsa chimene chidwi asayansi ndi nzika zoposa ziwiri zaka. Ngakhale kuti tikukhala mu m'badwo wa makompyuta ndi mapulogalamu zotsogola zambiri, zinsinsi zambiri za manambala yaikulu si anathana mpaka tsopano, pali ngakhale ena amene asayansi sindikudziwa momwe kufikako.

Primes - Ichi chikudziwika koma a pulayimale Inde masamu, anthu manambala achilengedwe amene anagawa popanda yotsala yokha ndi chimodzi ndi palokha. Mwa njira, ngati nambala zachilengedwe ndi divisible, koma pamwamba, mopitirira kwa aliyense, iwo akutchedwa gulu. Mmodzi wa wotchuka limati Lingaliro Lovomerezeka kuti chiwerengero gulu akhoza ankayimiridwa ngati yekha nkotheka mankhwala a primes.

A ochepa chidwi mfundo. Choyamba, unit ndi wapadera m'njira yakuti zoona, sikuli kwa losavuta kapena chiwerengero gulu. Pa nthawi yomweyo, gulu la sayansi akadali anaganiza kuvomereza makamaka pa gulu loyamba, kuyambira yokhala mwathunthu amakwaniritsa zofuna zake.

Kachiwiri, chabe chiwerengero, wormed gulu "primes" ndi mwachibadwa deuce. wina aliyense ngakhale nambala kuti adzafike kuno sangakwanitse, chifukwa, ndi tanthauzo, kuwonjezera pa ndekha ndi unit lagawidwa nalowa awiri.

manambala yaikulu, mndandanda wa zomwe, monga tatchulazi, n'zotheka kuyamba ndi munthu, kuimira ndi mndandanda wopandamalire monga wopandamalire, mofanana ndi manambala achilengedwe. Zochokera Lingaliro Lovomerezeka chachikulu masamu, tinganene kuti primes konse linasokonekera, ndi sizidzatha, chifukwa mukatero amatipeza udzasokonezedwa ndi chiwerengero cha integers positive.

manambala Simple samapezeka manambala zachilengedwe mosintha, monga zingaoneke koyamba. Mosamala kupenda iwo, ife athanso muzindikire zinthu zingapo, chidwi kwambiri umene imakhudzana ndi otchedwa chislami- "mapasa." Kuwatcha choncho chifukwa m'njira zovuta kuzimvetsa anali pakhomo pafupi wina ndi mnzake, Wangopatulidwira ngakhale-delimiter (zisanu, zisanu ndi ziwiri, khumi ndi naintini).

Ngati ife mosamala kuyang'ana pa iwo, tikuona kuti Uwerenge manambala awa nthawi zonse angapo atatu. Komanso, anagawa ndi anzanga atatu anachoka mu wotsala nthawi zonse ziwiri, ndi bwino - unit. Komanso, kufalitsidwa wokha mndandanda zachilengedwe a manambala akhoza ananeneratu, ngati alipo osiyanasiyana lonse la sinusoids vibrational mfundo zazikulu zimene anapanga ndi kugawa manambala atatu ndi awiri.

Primes osati phunziro kutseka chofufuzidwa ndi masamu ya dziko, koma akhala ndi bwino ntchito pokonza mizere yosiyanasiyana ya manambala, ndilo maziko Inter zina zotere, chifukwa shifrografii. Izo ziyenera anazindikira kuti nambala yaikulu masamu okhudzana ndi zinthu zimenezi, akuyembekezerabe yesani awo, mafunso ambiri si nzeru zaumunthu, koma tanthauzo othandiza.
