Answer:
Yes it is. It is divisible by both numbers because the sum of the digits that make up the number gives a multiple of 3 and 9.
Step-by-step explanation:
For a number to be divisible by 9, the sum of all the digits that make up that number must give a multiple of 9. If the number is divisible by 9, it is divisible by 3 as 3 is a factor of 9. Also, For a number to be divisible by 3, the sum of all the digits that make up that number must give a multiple of 3.
Therefore to know if 32643 is divisible by 9,
3 + 2 + 6 + 4 + 3 = 18
Since 18 is a multiple of 9, then 32643 is divisible by 3 and 9.
