Question

care sunt divizorii numerelor 126,275,3131,23023???

Answer 1

D126= 2,3,6,7, 9, 14, 18, 21, 42, 63

D275=1,5,11,25,55,275

D3131=1,31,101,3131

23023 = 23*1000 + 23 = 1001*23 = 7*11*13*23, si  toate sunt numere prime (7,11,13,23), atunci divizorii lui 23023 o sa fie: D23023 = {1, 7, 11, 13, 23, 7*11,  7*13, 7*23, 11*13, 11*23, 13*23, 11*13*23}

Answer 2

D₁₂₆={ 1,2,3,6,9,14,21,42,63,126}

D₂₇₅={1,5,11,25,55,275}

D₃₁₃₁ = { 1,31,101,3131}

D₂₃₀₂₃= { 1,7,13,11,23,77,91,161,143,299,1001,2093,3289,23023}
