Between 10,000 and 100,000 depending on the source. The ancient Greek historian and traveller Herodotus (c.450BC) was told it took 100,000 slaves 20 years to build the Great P â¦ yramid. Modern sources put the number at 10,000. Smaller pyramids built earlier and later must have took less time and fewer people to build.
