ANSWER

The greatest four digit number =9999

we can get the required number by following steps:

step 1 : Divide 9999 by LCM of 15,24 and 36 

Step 2 : Subtract result of step 1 from 9999.

Prime factorization :

15=3×5

24=23×3

36=22×32

LCM (15,24,36)= 23×32×5=360

Step 1 :  Dividing 9999 by 360, we get 279 as remainder.

Step 2 : subtract 279 from 9999

9999−279=9720 

the greatest number of four digit which is exactly divisible by 15,24 and 36 is 9720.
