Znajdź NWD i NWW liczb:
a) 300 i 990
b) 546 i 306



Odpowiedź :

300/:2                     990/:3

150/:2                     330/:3

75/:5                       110/:2

15/:5                         55/:5

3/:3                          11/:11

1                               1

NWD(300,990)=2*3*5=30

NWW(300,990)=(2*2*5*5*3)*3*11=300*33=9900

 

546/: 2               306/:2

273/:3                153/:3

91/:7                   51/:3

13/:13                  17/:17

1                          1

NWD(546,306)=2*3=6

NWW(546,306)=(2*3*7*13)*3*17=546*51=27846
