The max take off weight is 396,890 kgs.
This information should be available on the Boeing website or other avaition-related websites. For a quick answer, I will related my experiences from 1970's. Boeing certified the B747-200 to operate with General Electric CF6-50 engines. During take-off power, each GE engine could produce 56,000 lbs of thrust per enginer: or 224,000 lbs for a few minutes. Now, the larger B747-400 a/c have more powerful engines. Currently each engine on a Boeing 747-400 can generate a maximum of about 63,300 lbs of thrust. Accordingly, since this aircraft has four engines it can produce total thrust of about 253,000 lbs.
