To find out if something is divisible by 3: add up all the digits and then see if 3 can go into that number.
[tex]3+2+6+4+3=18[/tex]
Since 3 can go into 18, 3 can go into 32,643.
To find if a number can go into 9: same way with 3. If you add all the digits and that number is divisible by 9, the whole number is divisible by 9.
Since 18 can be divided by 9, 9 can go into 32,643.
So, to answer your question, 32,643 is divisible by 3 and 9.
