Rastavljanje na faktore

Prirodan broj se rastavlja na faktore tako što se deli sa najmanjim prostim brojem kojim je on deljiv. Postupak se nastavlja dok je to moguće. Na primer, broj 360 se rastavlja na faktore na sledeći način:

1. 360=2*180
2. 360=2*2*90
3. 360=2*2*2*45
4. 360=2*2*2*3*15
5. 360=2*2*2*3*3*5
6. 360=2*2*2*3*3*5*1
