Is 3784 divisible by 3?
NoA trick to use to see if a number is divisible by 3 is to add all of the digits together.3+7+8+4 = 22Take the 22 and if 3 will go into it, it is divisible by 3. Since 3 will not go into 22, then 3 will not go into 3784.A different example of this would be 3786.....3+7+8+6 = 243 will divide evenly into 24 because 3 x 8 is 24. So 3786 is divisible by 3.This also works for the number 9.8415, add digits together and get 18, so 8415 is divisible by 9.
