If z is an integer and z! is divisible by 340, what is the smallest possible value for z?

340=17*2*10
thus for z! to be divisible by 340, z! must have 17
z=17

Excause me, but 17 can not be divisible by 340. I think vice versa.

17 is not divisible by 340
if z! is to be divisible by 340 (=17*2*10) z! must contain 17.
Thus z must be atleast 17. Because if z<17, z! won't be divisible by 340
