Answer 2

Answer:

6782 is not divisible by 3

Step-by-step explanation:

I believe your Question was,

"Is 6782 is divisible by 3."

Now, we can solve this in 2 ways, either by looking into the divisibility rule or dividing it as usual, and if remainder comes greater than 0 then it is not divisible.

Divisibility method

We know that, each number has a divisibility rule that tells us directly even without dividing, if the number is divisible or not.

Now,

The divisibility rule of 3 states that, if the complete sum of a number is taken and if they add upto 3, 6 or 9 then that number is divisible by 3 or that number will be completely divided by 3.

We have,

6782

Sum = 6 + 7 + 8 + 2 = 23

But we must find the complete sum, that is, we must add further to get a single digit number,

= 2 + 3 = 5

Now, we know that 5 is not a multiple of 3 nor it is equal to 3, 6 or 9.

Thus,

6782 is not divisible by 3.

Division method

To find if its divisible we can just divide them, but this method is not recommended, as long numbers will take lots of time.

6782 ÷ 3

Hope it helped and believing you understood it........All the best
