WebFor any number A, it's modular inverse is any such number such that when you multiply this number by A (or if you multiply A by this number) you get 1. That is A ⋅ A − 1 = A − 1 ⋅ A = 1 ( mod c) For example, 3 ⋅ 5 = 1 ( mod 7) Thus 5 is the modular inverse of 3, and 3 is the modular inverse of 5 (specifically for mod 7 ).
