user_1, user_2 and user_3 each generate their own public-private
keypair.  So:

  Receiver_1 has public_key_1 and private_key_1
  Receiver_2 has public_key_2 and private_key_2
  Receiver_3 has public_key_3 and private_key_3

They then all send their public keys to a fourth user, "Sender" (who may
actually be one of the receivers, if you wish).

Sender then encrypts the file using the public keys of all the
Receivers.  For example:

gpg --recipient Receiver_1 \
    --recipient Reciever_2 \
    --recipient Receiver_3 \
    --encrypt-file file_to_be_encrypted

Each of the three recipients will then be able to decrypt the file using
their own private key.
