Please show explaintion for steps and the formulas used thank you.

Extracted text: Alice publishes her RSA public key: modulus n = 27455269 and exponent e = 191. (a) Bob wants to send Alice the message m = 27453912. What ciphertext does Bob send to Alice? (b) Alice knows that her modulus factors into a product of two primes, one of which is p = 5011. Find a decryption exponent d for Alice. (c) Alice receives the ciphertext c= 5329179 from Bob. Decrypt the message.
