Answers to Questions

How to calculate a modular inverse?

dCode uses the Extended Euclidian algorithm and arbitrary precision functions to get resulsts with bg integers.

3^-1 mod 11 is equivalent to 4 because 4x3 = 12 and 12 is equivalent to 1 modulo 11href.

The Euclidean algorithm is similar to that used in the calculation of GCDhref or the identity of Bezout.

What is the modular Inverse?

The value of the inverse modular of a by the modulus n is the value u such as $$ u \equiv a^{-1} \pmod n $$ $$ a u \equiv1 \pmod n $$

What does invmod mean?

The keyword invmod is the abbreviation of inverse modular.
