Which makes sense, as (in "real speak") a is the inverse of b if a*b == 1, i.e., a = 1/b. To find a, given b and p, requires the use of the "Greatest Common Divisor" (GCD) which returns the largest integer less than (or equal to) a (or) and b that divides a and b evenly.. If this integer is 1, then a and b are relative prime, since only 1 can … hm temp
