Let m be the largest integer that equals the product of its units digit and the sum of its digits, and let n be the largest integer that equals the product of its leading digit and the sum of its digits.

Find n-m.

• @bhaskar n is not 48
  in 48 leading digit is 8 and sum=12 so 48=!8*12

• its possible only for
  m = 45 ,
  45 = 5(4+5), 5 -> unit place and
  4+5-> sum of digits
  n=48
  48 = 4(4+8), 4->1st position no.
  4+8-> sum of digits
  n-m = 48-45 = 3
  3 is the answer
