5 power 16 + 125 power 5 can be written as 5 power 16 + ((5 power 3) power )5 = 5 power 16 + 5 power 15 - in this taking (5 power 15) as common it will be (5 power 15 )x ( 5 power 1 + 1) = (5 power 15 )x ( 5 +1) = 5 power 15 x 6 So the number is divisible by 5 and 6 also

Usually they don't ask such questions in exams which have more than one answer
