Question

determinati divizorii lui 930 reunit cu multiplii lui 930

Answer 1

D₉₃₀ = {1, 2, 3, 5, 6, 10, 15, 18, 30, 31, 62, 93, 155, 186, 310, 930}

M₉₃₀ = {0, 930, 1860, 2790, 3720, ...}

D₉₃₀ ∩ M₉₃₀ = {930}

D₉₃₀ ∪ M₉₃₀ = {0, 1, 2, 3, 5, 6, 10, 15, 18, 30, 31, 62, 93, 155, 186, 310, 930, 1860, 2790, 3720, ...  }

Answer 2

D₉₃₀={1,2,3,5,6,10,15,18,30,31,62,93,155,186,310,930⇒multimea divizorilor naturali ai lui 930;
M₉₃₀={930,1860,2790,.......}⇒multimea multipliilor naturali ai lui 930;
Dar in problema nu ne zice daca divizorii respectiv multiplii sa fie naturali pot fi si negativi(intregi).
Atunci D₉₃₀∪M₉₃₀={-930,-310,-186,-155,-93,-62,-31,-30,-18,-15,-10,-6,-5,-2,-1,................}
