Linear Programming magnitude error

Hello,

I have problem in using linear programming toolbox. When i input the parameter it say "LINPROG stopped because some objective or constraint matrix coefficients are too large in magnitude."

My equation is actually simple : 4.2e+218 X(1) + 3.5e+207 X(2) + 5.8e+218 X(3) + 6.7e+218 X(4) = 1

did i make any mistake in the input?

the input i write is shown below :

A=[1 1 1 1];
b=1;
f=[4.2e+218 3.5e+207 5.8e+218 6.7e+218]

x = linprog(f,A,b);
