we can use {https://www.alpertron.com.ar/ECM.HTM} to get a,b from n

a=416064700201658306196320137931 __ b=590872612825179551336102196593

n=245841236512478852752909734912575581815967630033049838269083 ct=219878849218803628752496734037301843801487889344508611639028

puy=(a-1)*(b-1)

e=3

d=inverse(e,puy)

flag=pow(ct,d,n)

print(long_to_bytes(flag))
