Je weet 100% zeker dat het getal eindigt op een 9. In elke tafel van 7 zit maar 1 getal dat eindigt op 3. Daarvan heb ik de eerste 12 opgeschreven (+6). Toen alles aangekruist dat -2 deelbaar was door 3. Dan is het gewoon een kwestie van heel snel wegstrepen, want je houdt er 4 over of zo.

Maar ik wil ook wel graag de beta-manier van berekenen zien, hoor :razz:

Er komt verder niets uit, dus hier dan een volgens mij wat minder tijdrovende oplossing:
Als je bij het gevraagde getal 1 optelt is het het kleinste getal dat door 8,7,6,5,4,3 en 2 deelbaar is. Het Kleinste Gemene Veelvoud, dat leren ze tegenwoordig toch nog wel op de basisschool hoop ik? In dit geval is dat 8x7x5x3 = 840. Het gevraagde getal is dus 839.
