WebRSA uses the Euler φ function of n to calculate the secret key. This is defined as. φ ( n) = ( p − 1) × ( q − 1) = 120. The prerequisit here is that p and q are different. Otherwise, the φ function would be calculated differently. It is important for RSA that the value of the φ function is coprime to e (the largest common divisor must ... WebSep 6, 2015 · This is the approach used in the influential book Concrete Mathematics by Graham, Knuth, Patashnik. This will give you 1/2 (mod3)=1/2. To work through your problem, you have a = 7 * (4/11) = 28/11, and b = 10. a / b = (28/11)/10 = 0.25454545... ⌊a/b⌋ = 0 b ⌊a/b⌋ = 0 * 0 = 0 a - b ⌊a/b⌋ = 28/11 - 0 = 28/11 This means your answer is 28/11.
