When the last digit is 4, the digit in the tens place can be 2, 4 ; the number of ways in the hundredth place and thousandth place can be 5 ways each. So the number of 4 digit numbers ending with 4 is 1 * 2 * 5 * 5 = 50. Therefore the total number of 4 digit numbers that can be formed that is divisible by 4 is 125.
