Question 117741
We already know that 18 is not divisible by 4 (you can divide 18/4 to get 4.5 and you can see that 18 is not a multiple of 4). 



The number 48 is divisible by 4 since 48/4=12. 



Since the number 52 is divisible by 4 (52/4=13), the number 452 is divisible by 4. 


Because 86 is not divisible by 4, 486 is not divisible by 4.



Finally, since 44 is divisible by 4, 844 is divisible by 4. 




note: All you need to check if a number is divisible by 4 is the last two digits of that number. For example, if I wanted to see if 1,003,485,020 was divisible by 4. I would simply take the last two digits 20 and see if it was divisible by 4. Since 20 is divisible by 4, the number 1,003,485,020 is divisible by 4. For further proof, divide 1,003,485,020/4 to get 250,871,255.
