1*2*3 = 3! -> yes, it's the definition
2*3*4 = 4! -> it's the definition of "!" again
4*5*6 = 5! -> because 6=1*2*3
8*9*10= 6! -> 8=2*4, 9=3*3, 10=2*5, so all composant from 2*3*4*5*6 is in
but 16*17*18 <> 7! -> sure, 17 is prime and no factor of 7! can be 17

You can find billions of random things like this in theory numbers, in fact
nothing interresting ...
