In Response To 'Re: No more memory available.'
---------
Changing your
F = (1.5*T*((Ψ*X)+(H*X*Y)))
to
F = (3/2*T*((Ψ*X)+(H*X*Y)))
to avoid questions about roundoff

and inspecting your simplified Eq1,Eq2,Eq3,Eq4 seems to hint that eliminating λ1 and λ2 might be a good first step.

Thus
eqns = Eliminate[{Eq1==0&&Eq2==0&&Eq3==0&&Eq4==0}, {λ1,λ2}]
gives a very reasonable
C==X^2+Y^2&&K==V-B X-M X^2-R X^2-A X Y+D X Y-O Y^2-R Y^2+Y Z

Then
Solve[eqns,{X,Y}]
does give lengthy solutions for X and Y using only reasonable amounts of time and less than 1GB of memory. I would not attempt FullSimplify on those.

You can then easily
Solve[Eq1==0&&Eq2==0, {λ1,λ2}]
and substitute your values for X and Y to obtain impressively large expressions for λ1 and λ2. I would not attempt FullSimplify on those.

Perhaps you can find something useful in this.
