Algorithm yekudzikisa nhamba kuita zvinhu zvakakosha
Kutanga, ngatirangarirei izvozvo nyore inhamba yechisikigo yakakura kupfuura zero inongopatsanurika yega uye imwe chete (“1” haisi yekutanga).
Kana paine vanopfuura vaviri vanopatsanura, nhamba inotariswa composite, uye inogona kuoreswa kuita chigadzirwa chezvinhu zvakakosha. Iyi nzira inodaidzwa factorization, ine matanho anotevera:
- Isu tinoita shuwa kuti nhamba yakapihwa haisi yekutanga. Kana iri kusvika ku1000, saka tafura inowanikwa mune imwe yakasiyana inogona kutibatsira neizvi.
- Isu tinoronga kuburikidza nenhamba dzese dzekutanga (kubva kudiki) kuti tiwane divisor.
- Isu tinoita kupatsanurwa, uye kune inoguma quotient tinoita danho riri pamusoro. Kana zvichidikanwa, dzokorora chiito ichi kakawanda kusvika tawana nhamba yepamusoro semhedzisiro.
Factorization mienzaniso
muenzaniso 1
Ngatiparadze 63 kuita zvinhu zvakakosha.
Sarudzo:
- Iyo nhamba yakapihwa inoumbwa, saka iwe unogona kuenzanisa.
- Mudiki mukuru divisor ndiye matatu. Iko quotient ye63 yakakamurwa ne3 ndeye 21.
- Nhamba 21 inopatsanurwawo ne3, zvichikonzera 7.
- Seven inhamba huru, saka tinomira pairi.
Kazhinji, iyo factorization inotaridzika seizvi:
Pindura: 63 = 3 3 7.
