I need to find all the elements in Z/80 that have multiplicative inverses. Z/80 is not a field, so I know not every element will have an inverse. Is there a shorter way than just writing out the ...
I'm working out some examples on multiplicative inverses. I understand how to solve for a multiplicative inverse using the Extended Euler's algorithm, but I don't understand the principles which ...
So the problem is this - we have a simple equation: (A * B) % N = X All numbers are large integers. We know B, N and X, is it possible for us to figure out the last factor A without checking every ...
I have a 64 bit algorithm that uses modular multiplicative inverse and coprime numbers, and I need to convert it to 32 bit. This math is not my area, and I cannot find an online calculator, so I hope ...
