Assuming the string the server is encrypting is the same flag, this is just Håstad's broadcast attack.
```pyfrom pwn import *from sympy.ntheory.modular import crtfrom gmpy2 import irootfrom Crypto.Util.number import long_to_bytes
ns=[]cs=[]for i in range(17):    r = remote('challs.n00bzunit3d.xyz', 2069)    e = eval(r.recvline().rstrip().lstrip(b'e = '))    cs.append(eval(r.recvline().rstrip().lstrip(b'ct = ')))    ns.append(eval(r.recvline().rstrip().lstrip(b'n = ')))    r.close()
M17 = crt(ns, cs)[0]print(long_to_bytes(iroot(M17,17)[0]))```
Flag: `n00bz{5m4ll_3_1s_n3v3r_g00d!}`
