a= 378979003;
b= 1.443e-5;
The result of a*b is 5468.7 but I'm very interested in higher precision (such as 5468.6670). How to achieve those precision?

The point of both answers is that MATLAB never did "lose" any precision. You did not see those extra digits because of the wrong format for your goals.

You can check that a*b and 5468.7 are not equal
a*b==5468.7
Now try this
format long
c=a*b
