K sp of any salt is equal to the multiplication of concentration of its ions.
‌‌ For ‌AgCl→Ag++Cl−
K sp=[Ag+][Cl−]
‌1.8×10−10=10−10[Cl−]
‌[Cl−]=‌

1.8×10−10

10−10

=1.8
Similarly, for AgBr
[Br−]=‌

5×10−13

10−10

=5×10−3
For AgI
I−=‌

8.3×10−17

10−10

=8.3×10−7
Lesser is the concentration of ion, more easily they get precipitated.
So, order of precipitation is
AgI >AgBr>AgCl
