Mohammed Karrar, 38, and brother Bassam Karrar, 34, will serve a minimum of 20 years and 15 years respectively.
Brothers Akhtar Doghar, 32, and Anjum Doghar, 31, were both given minimum terms of 17 years, at the Old Bailey.
The men’s offences included child rape and trafficking, between 2004 and 2012. A fifth man was also jailed for life.
Kamar Jamil, 27, who was found guilty of charges including rape and arranging child prostitution, was told he would serve at least 12 years.
Jurors heard at the men’s trial at the Old Bailey how six girls, aged at the time between 11 and 15, were plied with alcohol and drugs before being forced to perform sex acts.
Some were beaten and burned.
The court heard how the men – two of east African origin and five of Pakistani origin – identified vulnerable girls for abuse and then groomed each one of them until they were under the control of the gang.
They were then each either abused by the men themselves, given to the men’s friends or offered at a price to others who were not on trial.
The girls were mostly chosen because their unsettled or troubled lives made them easier to manipulate.
These Muslims never groom Muslim girls..
