Divisibility by 6



6 is the second composite number after 4.

Is this number divisible by 6?
Since 6 is composite, we all know that its prime factorization is 2 x 3, right? So, a number has to fit in those two numbers, or should be even and divisible by 3.

You can do this another way as well. Seperate the ones digit from the rest of them. Ignore it for now, but dont completely forget it. Add the rest of the digits together, then multiply the result by 4. Add the ones digit from before to what you got. The result should be divisible by 6.
