From the hint 1
The common multiples of 3,4,5 are:
60,120,180,240,300,
360.420,480,540,600,
660, 720, 780, 840,900,
960
60 cannot be because it is a two-
digit number.

 

 Based on hint 3, multiples with any
of the digits 1,4,6,8 are excluded.

 

 120, 180, 240, 360, 420, 480, 540,
600, 660, 780, 840, 960 are
excluded.

300, 720 and 900 remain

 

 Based on hint 2
BCD is divisible by 5
The digit D can be 0 or 5 ,But since
it is divisible by 8, it cannot be 5.
Therefore D is 0
The 4-digit code ABCD can be:
3000 7200 or 9000
BCD can be 000 or 200
000 not divisible by 8

 200 is divisible by 8

 

 Correct answer is 7200
