Add together the digits of the number to be divided by 3. If the sum is 3 or a multiple of 3 then the number is divisible by 3. Example : 5681 ; 5 + 6 + 8 + 1 = 20 which is not a multiple of 3 so 5681 is NOT divisible by 3. 477 ; 4 + 7 + 7 = 18 which is a multiple of 3 so 477 is divisible by 3. NOTE : When adding the digits, the digits of the total can be summed to determine if the original number is divisible by 3. In the example 4 + 7 + 7 = 18 then 1 + 8 = 9, and 9 is a multiple of 3 so confirming that 477 is divisible by 3.

of course its divisable by all 3... if you divide by 3 or 9 you get a whole number answer if thats what you meant

add up all the individual digits in the number. if the answer has more than one digit, add the digits of the answer up. keep doing this till you get a single number. if the answer is 3, 6 or 9 the number is divisible by 3. eg 477 4 + 7 + 7 = 18 1 + 8 = 9 answer is 9, so 477 is divisible by 3

It is a composite Because 477 is divisible by 3 and because of that.... it makes it a composite because it is divisible by 1 and 3 PS I am just an ordinary 6th grade girl :)
