The four were convicted last August in Grand Rapids federal court and sentenced this week.
The longest sentence of life in prison for premeditated murder went to 36-year-old Charles Lewis Sr., who authorities say fired the rifle shots that killed Shayla Johnson.
Mustafa Al-Din, 26, was sentenced to 50 years; his 25-year-old brother, Walee Al-Din, was sentenced to 60 years; and Raphael Crenshaw, 24, was sentenced to 47½ years in prison.
Prosecutors said they were tied to the "Block Burners" gang and wanted to kidnap Johnson to force her boyfriend to turn over cash and drugs.
Four others were sentenced earlier.
