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 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.
To determine which number is divisible by 3, 6, and 9, we need to check if the sum of the digits of each number is divisible by 3. For 369: 3+6+9 = 18, which is divisible by 3, 6, and 9. Therefore, 369 is divisible by 3, 6, and 9. For 246: 2+4+6 = 12, which is divisible by 3 but not by 6 or 9. Therefore, 246 is divisible by 3 but not by 6 or 9. For 468: 4+6+8 = 18, which is divisible by 3, 6, and 9. Therefore, 468 is divisible by 3, 6, and 9. For 429: 4+2+9 = 15, which is divisible by 3 but not by 6 or 9. Therefore, 429 is divisible by 3 but not by 6 or 9. Therefore, the numbers 369 and 468 are divisible by 3, 6, and 9.
72,344 is not evenly divisible by 3 or by 6 or by 9.
42 is divisible by 2, 3 and 6 but not by 9.
