Odpowiedź:
140 i 21
140 = [tex]2^{2} *5*7[/tex]
21 = 3 * 7
NWD (140,21) = 7
NWW (140,21) = [tex]2^{2} *3*5*7=420[/tex]
72 i 150
72 = [tex]2^{3}*3^{2}[/tex]
150 = [tex]2*3*5^{2}[/tex]
NWD (72,150) = 2 * 3 = 6
NWW (72,150) = [tex]2^{3} *3^{2} *5^{2} =1800[/tex]
306 i 408
306 =[tex]2*3^{2} *17[/tex]
408 = [tex]2^{3} *3*17[/tex]
NWD (306,408) = 2 * 3 * 17 = 102
NWW (306,408) = [tex]2^{3} *3^{2} *17=1224[/tex]
