i am got 3.6 after i divide 10^6 why should i divide by it

Using your values: \[\Large F_g=G\frac{M}{r^2}\]\[\Large F_g=6.67*10^{-11}m^3kg^{-1}s^{-2}\frac{6.6*10^{23}kg}{(3450000m)^2}=3.67m/s^2\] And that's about right. If you look it up online you'll see that the force of gravity on Mars is about 38% that of Earth:\[0.38*9.8m/s^2=3.7m/s^2\]
