Ope hujus Tabea; SI Proxonatur numerus 539454600; Facile resolvetur hie
in Primos illos ex quibus componitr. Nam primo, propter duas Ciptras Fina-
les, manitectum est, abscistis Ciphris, bis per 2, ec bis per 5, diridi polse. Tum,
quia, post abscistas Ciphras has, numerus adhuc Par est, potest tertia vice per 2
diridi; indeque CmCrSCL 2697273. Tum, si numerus hic Pabella limites non
excederet; quari porer inde, quis Primus numerus iplum dividat. Sed, quoniam
major est quam uc ibidem hrabeatur; invenio, consideratione habita, quod ex fi-
suris ejus promiscue sumpris, abjecto 9 quories tieri porest nihil supereste; adeo-
que polle illum per odiridi. Duo facto, quotiencem 299697 Timiliter examino.
invenioque, post abjectum o quories tieri possie, Tupereste 6; adeoque illum divi-
sibilem adtue esse, non quidem per o, led salcem per 3:  Ouotientem tore
99899; qui jam intra Pabella limites reducitur. Adeoque (abique Pencamine
Facto per numCrOS 7, FP, F3, Erc.) invenio, inspecta Tabella, Poste hunc Per 283
diridis (non autem per minorem Primum;) e quorientem Fore 353, alium Pri
mum. Indeque concludo, resolrendum numerum 53945460O == Z X Z. X 2. X 3X 5
X3X5X5 X283X353.
Si autem, pro 99899, prodiistet numerus major quam quo extendit Pabella, et
qui per 2, 5, aut 3, non possit diridi: oporteret (pro defectu Tabula Patis am
DlX) centamen Facere per Sequentes numeros PrimOs, 7, TY, F3, _cc. donec, ope
calium tentaminum, reducatur intra Pabellae limites. Verum, si nullus interea
dirisor occurrat antequam ad talem Primum perreniatur qui major sit radice
quadratica numeri examinandi; concludendum erie, cum esse Numerum Primum,
nec posse ulcerius resolvi.
