Is 3091 divisible by 9?
No. To check divisibility by nine, sum the digits. If they add up to 9 (or a multiple of 9) then the number is divisible by 9. This trick works for 9 divisibility and 3 divisibility. In this problem: 3 + 0 + 9 + 1 = 13, which is not divisible by 9. Suppose the number was 3591: 3+5+9+1=18, which is divisible by 9 (you can check 1+8=9). You can keep summing the digits of the new numbers till you get to a number which is either 9 or some other number. (If it's 3 or 6, then the number is divisible by 3)
