these questions come up often in my cryptography module an eam in which i have to take soon. I know that its inverse is that number raised to the power of the number of integers less than 784 coprime with 784 minus 1. However this invloves factorising large numbers, 784 is easy as its a square but is there an easier (quicker) method as time is a factor
