Are you sure that's right or are you off by an order of magnitude?

Boeing 747 - Wikipedia

747-400ER - 4 x 62,100lb or 4 x 63,300lb thrust = 248,400lb or 253,200lb thrust
747-8 - 4 x 66,500lb thrust = 266,000lb thrust.

He's right on the money, and definitely not out by an order of magnitude.

I was a 747 Captain for 15 years and have maybe something over 10,000 hrs in the left seat of one and got to fly every production model (including the Dash-8/Intercontinental and Dreamlifter) except an SP. A truly brilliant airframe, though the progression of models incorporated refinements. Engines, it's engines that really determine the commercial success of an airplane, that and the wing.

My daughter is a glacier pilot on Denali and now flies the Garret powered Turbine Otter, rather amazing what that power plant has done to the utility of that airframe.

Engines!
