Hi is there a general formula to find the inverse modulo of "a modulo n"...
i know its denoted as and
for example if a=29 and n = 78 then the inverse is 35 since: 29.35 = 1 mod 78...
(a)
but HOW DO U CALCULATE THE INVERSE? is there a formula?? please help me out here?
(b)
and how can this be used to solve 43 modulo 125, hence solve 43x = 3 mod 125
thanks
