[enzocreti]

pg(215) and pg(541456) are probable primes where 215 and 541456 have the same residue mod 41, the residue is ten. 215 and 541456 are multiples of 43,


215/307 and 541456/307 have also the same decimal periodic expansion 0.7003257...(lenght of the period 153)


consider the fraction:


A/307


A integer


for which values of A, A/307 has a decimal periodic expansion of 0.700325...?


Surely 215 and 541456 ...are there other values of A?


A=1763*307*k+215 they have the same decimal periodic expansion 0.700...
