========================
aimwe have to find If P416 is divisible by 11, find the value of smallest natural number P
=>first let us know divisibility by 11
=>if the difference of the alternating sum of digits of the number is a multiple of 11,then it is divisible by
let us explain it more
=>examole -121
=>(1-2) (1)
=>-11
-11 is divisible by 11
so 121 is divisible by11
here the number is p416
so (p-4) (1-6)
=>(p-4) ( -5)
so the number will end with 5
the least multiple of 11 ending with 5 is 55
so ( p-4) should be =5
=> p -4 =5
=> p = 5+4
=>p = 9
so the number is 9416
