The RSA ciphertext 97618045 was encrypted using public key (e, n) = (5, 105679573). There is reason to believe that the prime factors of n were insecurely chosen to be too close together. Use this insight to factor n and hence decrypt the message. Note: You are expected to use the specific method described in lecture for recovering the factors of an RSA modulus when its prime factors are too close together.
