input
6 6
1 2
2 3
2 4
4 3
5 6
4 5
output
1 2 4 6 5 3
This output isn't correct because for second flight (2, 3) gcd is equal to 2 != 1.

"If there are several FLIGHTS that depart from one AIRPORT then the greatest common divisor of their flight numbers should be equal to 1."
Why did you calculate gcd for the second flight? Output is a numbers of flights, not numbers of flights.
May be you should do this for the second airport. However gcd of the flight numbers of the second airport is gcd(1,2,4) = 1.
P.S. I think output is not right because gcd of the flight numbers from the airport #3 is equal to 2.
