I like to start by dividing the given number by 2, unless a larger factor is evident.

1386 = 2(693).  It's pretty obvious that we can divide 693 by 3:  693=3(231).

Then we have 1386 = (2)(3)(231).  Try the same procedure.  Does 231 have any integer, prime factors?  See how far you can take this factoring.
