How many 4 digit numbers divisible by 4 can be formed from the digits 1, 2, 3, 4, and 5?
I have a math problem I need help with. How many 4 digit numbers divisible by 4 can be formed from the digits 1, 2, 3, 4, and 5?
To form a 4 digit number that is divisible by 4, the last two digits of the number must be divisible by 4 as well. There are a total of 5 choices for the last digit of the number (2 or 4), and 2 choices for the second to last digit of the number (2 or 4). The first two digits can be any of the 5 digits (1, 2, 3, 4, or 5). Therefore, the total number of 4 digit numbers divisible by 4 that can be formed from the digits 1, 2, 3, 4, and 5 is 5x2x5x5 = 250.
