Answer:

the greatest four digit number is 9999

hcf of 12,16,24,28,36=4

9999÷4 we get remainder as 3

subtract 3 from 9999,we get

9996,which is the answer

Answer 2

Greatest 4digit no.is 9999 so
9999/4=2499.75 if we subtract 1 from 9999 then it will be 9998 and
9998/4 =2499.5
If we subtract 2from 9999it will be 9997
9997/4= 2499.25
If we subtract 3 from 9999 then it will be 9996
9996/4=2499 so largest 4 digit no.is 9996 by which 4 is divisible
