Time consumption in loop

In my work using Chinese remainder theorem as

C = num2cell(reshape(n, 4, 65536), 1); % n is an array of 262144 elements
for i=1:65536
ga=[311 313 317 293];
[bx by] = meshgrid(ba, ba);
bb = gcd(bx,by)-diag(ba);
pp = ~sum(sum(bb>1));
xo = by-diag(ba-1);
Mk = prod(xo);
[Gk, nk, Nk] = gcd ( ba, Mk ) ;
Sum_ga_Nk_Mk = sum ( (ga .* Nk) .* Mk ) ;
f1(i) = mod(Sum_ga_Nk_Mk,prod(ba));

The time consumption for this loop is quite long as the loop is repeated for 65536 times
Can you help me for reducing it??
