(478-P) , (392-P) and (263-P) should be divisible by N. If 2 numbers are divisible by N, then their difference is also divisble by N. Hene, (478-P)-(392-P) is divisible by N. And, (392-P)-(263-P) is divisible by N. So, 86 and 123 are divisble by N. Hence, N can only be 43. And 478=43*11+5. so, P=5.
