By doing the math in your head on a piece of paper or with your fingers. You should know 3, 6, and 9 are multiples of three, but for 2-digit numbers or larger you can add the digits and if they equal 3, 6, or 9 then they are multiples of 3. For example, 15 would be 1 + 5, which is 6, so it's a multiple of 3.

6 significant digits.
I suggest you do the divisions. If you get an integer, it is a multiple. If you get digits after a decimal point, it is not.18 18 is a multiple of 6 because it can be evenly divided by 6 to equal 3. 20 is not a multiple of 6 because it cannot be evenly divided by 6. 20/6 = 3.3333... .
6.0?
The answer is 6. (Here, the no. of digits = 1. Thus, Six times the no. of digits= 6 x 1 = 6)

If a number is divisible by 2 (an even number) and 3 (the sum of the digits is divisible by 3) then the number is divisible by 6.
If you add up the two digits and they make either 3, 6, or 9
They're all multiples of 1, 2, 3 and 6.

There are 31 of them.
The digital root is the sum of all the digits in an integer, with the process repeated if required. The digital root of all multiples of 3 are themselves multiples of 3. Their fully reduced values are 3, 6 or 9.
16 is not equal to 312. Other variations of these digits, such as 1/6 and 3/12 are not equal either.
