The fugacity coefficient is defined as the ratio fugacity/pressure. For gases at low pressures (where the ideal gas law is a good approximation), fugacity is roughly equal to pressure. Thus, for an ideal gas, the ratio Φ = f/P between fugacity f and pressure P (the fugacity coefficient) is equal to 1.

As pressure approaches zero all gases become ideal, therefore,
f->p as p->0 and therefore (f/p)->0.
f------>fugacity.
p------>pressure.
f->p as p->0 and therefore (f/p)->0.
f------>fugacity.
p------>pressure.

As pressure approaches zero since gas approaches ideal behavior the ratio of fugacity and pressure becomes unity.

F/P is equal to fugacity coefficient.
For ideal gas P = 0 then fugacity coefficient is 1 and so that f = p.
For ideal gas P = 0 then fugacity coefficient is 1 and so that f = p.
