owners are deceased and left no will

my grandparents are both deceased and expired without putting a legal will in place for their children to legally have their rights to the property left in question. to this union seven children was born. since their death, three children has expired (two with surviving children; one with none). my mother who is one of the remaining surviving children (four) who now resides in the home and has been totally responsible for all expenses regarding the home, property, etc. for many years. mainly because the other siblings now own their own homes, properties, etc. (in-state/out-state) and will in no way move back home to call the property in question as their main place of stay. i'm being told that the best things to do with the home and property is to do a quit claim deed to claim ownership in my mother's behalf. please help me with a legal answer to pursue the right steps to take with this matter. thank you.
