• 24 = 3 x8, where 3 and 8 co-prime.
  
  Clearly, 35718 is not divisible by 8, as 718 is not divisible by 8.
  
  Similarly, 63810 is not divisible by 8 and 537804 is not divisible by 8.
  
  Consider option (D),
  
  Sum of digits = (3 + 1 + 2 + 5 + 7 + 3 + 6) = 27, which is divisible by 3.
  
  Also, 736 is divisible by 8.
  
  3125736 is divisible by (3 x 8), i.e., 24
