Given four digits are 5 , 9 , 8 , 7

For smallest possible number without repeating  , best way is to arrange the digits in ascending order that is smallest  digit should come on left most side and greatest one should come on right side.

in our case on rearranging number in ascending order we get 5 , 7 , 8 , 9 and hence smallest required number is 5789 and digit at 100's place is 7.
