What is the share of each heir among a mother, a grandfather, a full sister, and two paternal half-brothers?

If the deceased leaves behind only a mother, a grandfather, a full sister, and two paternal half-brothers, then the mother receives one-sixth due to the presence of a group of siblings. The grandfather receives one-third of what remains after the mother's share, as this is more beneficial for him. The full sister receives half, and the two paternal half-brothers receive what remains of the estate after the shares of the mother, grandfather, and full sister. The estate is divided into thirty-six shares: the mother receives six shares, the grandfather ten shares, the full sister eighteen shares, and each paternal half-brother receives one share.
