Milyen egész számmal tudom elosztani a 389764-et (csak 11000-19000-ig) úgy, hogy a kapott eredmény, maximum 2 tizedesvesszőig terjedjen ki?

Prímtényezőre bontod, és abból meg tudod találni az osztókat:

o1:={1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 139, 200, 278, 400, 556, 695, 719, 1112, 1390, 1438, 2224, 2780, 2876, 3475, 3595, 5560, 5752, 6950, 7190, 11120, 11504, 13900, 14380, 17975, 27800, 28760, 35950, 55600, 57520, 71900, 99941, 143800, 199882, 287600, 399764, 499705, 799528, 999410, 1599056, 1998820, 2498525, 3997640, 4997050, 7995280, 9994100, 19988200, 39976400}

Az osztás után kapott hányadosok:

o3:={399760, 199880, 99941, 79953, 49971, 39976, 24985, 19988, 15991, 9994.1, 7995.3, 4997, 3997.6, 2876, 1998.8, 1438, 999.41, 719, 575.2, 556, 359.5, 287.6, 278, 179.75, 143.8, 139, 115.04, 111.2, 71.9, 69.5, 57.52, 55.6, 35.95, 34.75, 28.76, 27.8, 22.24, 14.38, 13.9, 11.12, 7.19, 6.95, 5.56, 4, 2.78, 2, 1.39, 1, 0.8, 0.5, 0.4, 0.25, 0.2, 0.16, 0.1, 0.08, 0.05, 0.04, 0.02, 0.01}
