Odpowiedź:
a) 84 i 90
84 = [tex]2^{2} * 3^{1} *7^{1}[/tex]
90 = [tex]2^{1} * 3^{2} *5^{1}[/tex]
NWD (84, 90) = [tex]2*3=6[/tex]
NWW (84, 90) = [tex]2^{2} *3^{2} *5*7[/tex] = 1260
b) 270 i 700
270 = [tex]2^{1} *3^{3} *5^{1}[/tex]
700 = [tex]2^{2} *5^{2} *7^{1}[/tex]
NWD (270, 700) = [tex]2*5=10[/tex]
NWW (270, 700) = [tex]2^{2} *3^{3} *5^{2} *7=18900[/tex]
c) 735 i 252
735 = [tex]3^{1} *5^{1} *7^{2}[/tex]
252 = [tex]2^{2}*3^{2} *7[/tex]
NWD (735, 252) = [tex]3*7 =21[/tex]
NWW (735, 252) = [tex]2^{2} *3^{2} *5*7^{2} =8820[/tex]
d) 294 i 385
294 = [tex]2*3*7^{2}[/tex]
385 = [tex]5*7*11[/tex]
NWD (294, 385) = 7
NWW (294,385) = [tex]2*3*5*7^{2}*11=16170[/tex]
