Numerele 47.53.64impartite la acelasi numar natural nenul n dau resturile 2,3,4 .Determinati n

Răspuns :

n=5 deoarece
[tex] \frac{47}{5} [/tex] = 9 rest 2
[tex] \frac{53}{5} [/tex] = 10 rest 3
[tex] \frac{64}{5} [/tex] = 12 rest 4

[tex]47=x\cdot c_1+2|-2\\ 53=x\cdot c_2+3|-3\\ 64=x\cdot c_3+4|-4\\ x\ \textgreater \ 4\\ 45=x\cdot c_1\\ 50=x\cdot c_2\\ 60=x \cdot c_3\\ x |(45,50,60)=5; x\ \textgreater \ 4\\ x=5[/tex]
