Formula:

The Multiplicative Inverse (Reciprocal) of a number x is simply:

1 / x

The Modular Multiplicative Inverse of a (mod m) is a number x such that:

(a * x) % m = 1

Where:

  • x = The number for which to find the reciprocal.
  • a = The number for which to find the modular inverse.
  • m = The modulus.
