Answer:

The given number is 98765*8

=> Let * be the x ,

the number become 98765x8.

=> divisibility rule of 8 : alternate adding and subtracting the digits, and if the result is the multiple of

8, then the original number is a multiple of 8

=>( 9 + 7 + 5 + 8 ) - ( 8 + 6 + x)

= 15 - x

=> 15 - x = 8

=> x = 7

=> 7 is the least value must be given to * so that the number 987658 is divided by 8
