To check for divisibility by 6 you need to check for divisibility by 2 and by 3.
Divisibility by 2: If the number ends with a 0, 2, 4, 6 or 8 it is divisible by 2. If it is not then it is not divisible by 2 and so cannot be divisible by 6.
Divisibility by 6: If the digital root is divisible by 3 then the number is divisible by 3. If it is not then it is not divisble by 3 and so cannot be divisible by 6.
The digital root is simply the sum of all the digits in the number. And, if the answer has more than 2 digits, you can repeat the process as many times as you like.
For example, 7987
7+9+8+7 = 31
3+1 = 4
So the digital root of 7987 is 4. That is not divisible by 3 and so neither is 7987.

To determine if a number is divisible by 6, we need to check if it is divisible by both 2 and 3. The number 34614 is divisible by 2 because it is even (the last digit is even). To check if it is divisible by 3, we sum the digits: 3 + 4 + 6 + 1 + 4 = 18, which is divisible by 3, so 34614 is divisible by 3. Therefore, 34614 is divisible by 6. To check if it is divisible by 9, we sum the digits again: 3 + 4 + 6 + 1 + 4 = 18, which is divisible by 9, so 34614 is divisible by 9 as well.
To determine if 1728 is divisible by 6, we need to check if the sum of its digits is divisible by 3 and if it is an even number. The sum of the digits of 1728 is 1+7+2+8=18, which is divisible by 3. Additionally, the last digit of 1728 is 8, which is an even number. Therefore, 1728 is divisible by 6.
No odd number can be evenly divisible by 6. Since 6 is divisible by 2, any number that is divisible by 6 will automatically be divisible by 2.
Quickly check to see whether it's divisible by both 2 and 3. Here's how to do that easily: -- The number is divisible by 2 if it's an even number . . . the last digit is 2, 4, 6, 8, or 0. -- The number is divisible by 3 if the sum of its digits is divisible by 3.
To determine if 2106 is divisible by 6, we need to check if 2106 is a multiple of 6. To do this, we can use the divisibility rule for 6, which states that a number is divisible by 6 if it is divisible by both 2 and 3. First, we check if 2106 is even (divisible by 2), which it is because the last digit is even. Next, we calculate the sum of the digits of 2106 (2+1+0+6=9) and check if this sum is divisible by 3. Since 9 is divisible by 3, we can conclude that 2106 is divisible by 6.
