5 040 – Greek philosopher Plato gave this number as the population of an ideal city.
This number has several factors, which implies an efficient division of population for the sake of land distribution, taxes, war etc.
In fact,
5, 040 = 7! = (1)(2)(3)(4)(5)(6)(7)
5, 040 = (24)(32)(51)(71)
Thus, 5 040 has (4+1)(2+1)(1+1)(1+1) = 60 factors








But does that 5040 include children? slaves? women?
No, Plato didn’t include women, slaves or children. The actual number of inhabitants should be around 50 000 (Knack & Azfar 2000:3)
