A naive method of finding a modular inverse for A (mod C) is: step 1. Calculate A * B mod C for B values 0 through C-1. step 2. The modular inverse of A mod C is the B value that makes A * B mod C = 1. Note that the term B mod C can only have an integer value 0 through C-1, so testing larger values for B is redundant. lorraine kelly illnessWebϕ ( n) = n ( 1 − 1 p 1) ( 1 − 1 p 2) ⋅ ⋅ ⋅ ( 1 − 1 p r) .
