Given:

Divisibility rule of 8

Concept used:

Divisibility rule of 8: When the number made by the last 3 digits of a number is divisible by 8 then the number is also divisible by 8.

Apart from this if the last three or more digits of a number are zero then the number is divisible by 8.

Calculations:

Considering the given number:

The last 3 digits are 326 and so, for it to be completely divisible by 8 we have to deduct 6 from the given number.

⇒ (148109326 - 6) / 8

148109320 / 8

⇒ 1763655

Hence, the smallest number that can be subtracted from 148109326 so that it becomes divisible by 8 is 6.
