from 8 digit number 1,2,3,4,5 repitions r allowd and must by divisible by 4.

• the last two digits possibilities are 12,24,32,44,52 -> 5 possibilities
  and first 6 digits possibilities are 5^6
  so total possibilities are 5^7

• if a number should divisible with 4 means. The last 2 digits of the number should divisible by 4.
  In the last 2 digits of an 8 digit number using 1,2,3,4,5 should have these combinatios
  12
  24
  32
  44
  52
  there are 5 possibilities
  and the first 5 digits may be any of 5 numbers.
  so the number of possibilities are 5^5*5=5^6

• last two digit of an eight digit number divisible by 4 should have these combination
  12,24,32,44,52 -> 5 possibilities
  
  so the number of combinations are 5^7*5=5^8

• The Eight digit no is 52341524.
  52341524/4=13085381.
  so the Eight digit no and answer is: 52341524.

• My earlier explanation is some mistake.
  The Eight digit no is 52341524.
  52341524/4=13085381.
  so the Eight digit no and answer is: 52341524.
  if any 8 digit no to take then last two digit no is divided by 4. That possibilities are 12,24,32,44,52. so the ans is 5 possibilities. To take this combination of 8 digit no is divided by 4.

• 5*5*5*5*5*5*5=5^7
  the number divide by 4 is that last two digit should divisible by 4
  12,32,24,52,44= 5 ways
