how to write the tf in this case then which method should I use to find state space?!

No, the internal representations automatically normalize the leading coefficient.

You can define the transfer function as follows:
den = [10 7.4 337.3 171.1 5498.1];
sys1 = tf([0 0 19.04 15.03 933.1],den);
sys2 = tf([0 0 -47.6 14.73 -1.03],den);
sys3 = tf([0 0 -47.6 13.8 2.2],den);
sys4 = tf([0 0 152.4 56.2 3739.2],den);
sys = [sys1 sys2; sys3 sys4];
Now to get the state space co-efficients use the ss function :
State_space_coefficients = ss(sys)
