Feem ntau, yog tias koj muaj qhov tseem ceeb ntawm tus lej n, tom qab ntawd txhawm rau suav pes tsawg tus divisors nws muaj, koj muab tag nrho cov exponents hauv qhov factorization, ntxiv 1 rau txhua, thiab tom qab ntawd muab cov "exponents + 1" ua ke.
Yuav ua li cas thiaj nrhiav tau qhov zoo sib faib?
Yog tias peb xav nrhiav qhov zoo sib faib rau tus lej n, peb tsuas yog coj tustus lej 1, 2, 3,…, n, faib n los ntawm txhua tus, thiab cov uas faib sib npaug ua cov txheej txheem zoo sib faib rau n.
Yuav ua li cas thiaj nrhiav tau tus lej faib?
Tus qauv rau kev suav tag nrho cov lej ntawm tus lej 'n' qhov twg n tuaj yeem sawv cev raws li lub zog ntawm tus lej tseem ceeb yog qhia raws li. Yog N=paqbrc. Tom qab ntawd tag nrho cov lej sib faib=(a + 1)(b + 1)(c + 1).
Tus lej ntawm qhov zoo yog dab tsi?
Tus divisors (lossis yam) ntawm tus lej zoo yog tus lej uas sib npaug sib npaug. Piv txwv li, qhov sib faib ntawm 28 yog 1, 2, 4, 7, 14 thiab 28. Tau kawg 28 kuj tseem faib tau los ntawm qhov tsis zoo ntawm txhua qhov no, tab sis los ntawm "divisors" peb feem ntau txhais tau tias qhov zoo divisors.
Dab tsi yog qhov zoo ntawm 372?
(a) (372=(2^2)(3)(31)) (b) Cov txiaj ntsig zoo ntawm 372 yog 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, thiab 372.
