[tex]111 \times 64 + 28 \times 111 - 111 + 91 \times12 = [/tex]

[tex] = 111 \times (64 + 28 - 1) + 91 \times 12[/tex]

[tex] = 111 \times 91 + 91 \times 12[/tex]

[tex] = (111 + 12) \times 91[/tex]

[tex] = 123 \times 91[/tex]

[tex] = 11193[/tex]

Răspuns:

111 ×64+28×111 - 111+91×12=

dam factor comun 111

111(64+28-1)+91·12=

111·91+91·12=

dam factor comun 91

91·(111+12)=

91·123=11193
