https://doi.org/10.1007/978-3-030-75305-4A famous and important theorem of number theory due to Fermat (c. 1640) gives, among other uses, a different way to find the inverse of a nonzero element of ?., . prime. We have already seen how to find the inverse of [.]. by solving . +. = 1, using Euclid’s algorithm and Bezout’s identity.

https://doi.org/10.1007/978-3-319-64030-3This is a famous theorem of number theory, so called because it was known to the ancient Chinese. Its proof is another application of the fact that the greatest common divisor of two numbers can be written as a linear combination of the two numbers.
