Question

Is 26,341 divisible by 3?

Answer 1

To find if a number is a divisible by 3, follow this process:

Add all the digits up.

2 + 6 + 3 + 4 + 1 = 16

16 is not divisible by 3.

Therefore, 26,341 is NOT divisible by 3.

Answer 2

No.  26,341 is not evenly divisible by 3 .

Here's the trick you can use to decide this
just by looking at a big number:

==>               If a number is divisible by 3, then the
                     sum of its digits is divisible by 3.

I've never taken the trouble to figure out why this works,
but it does work.  I didn't make it up.  It's widely known.

So let's look at  26,341 .

The sum of the digits is  (2 + 6 + 3 + 4 + 1)  =  16 .

16  is not divisible by  3 , so  26,341  is not divisible by  3 .

Is that cool or what !
