If the sum of all the digits is divisible by 9, then the entire number is divisible by 9! For example: 9,728,127 is divisible by 9. 9+7+2+8+1+2+7=36, and I know 36 is divisible by 9. Therefore, the whole number is. 982 is not. 9+2+8=19. 19 is not divisible by 9.
Works for really huge numbers too. 3,456,245,190,769,984,245,865,992,831 The sum of the digits is 144. Unsure if that works? Find the sum of THOSE digits (and keep doing that until you get something that you KNOW is divisible by 9). 1+4+4=9. That means the whole huge number is divisible by 9!
