what is the sum of factors of 16!...??

• 1!=1, factors of 1=1 sum of factors=1 (half of 2!)
  2!=2, factors of 2=1,2 sum of factors=3 (half of 3!)
  3!=6, factors of 1=1,2,3,6 sum of factors=12 (i.e. half of 4!)
  4!=24, factors of 1=1,2,3,4,6,8,12,24 sum of factors=60.....half of 5!
  so.....
  sum of factors of 16! will be (17!/2)
