Question

test the divisiblity of the following numbers by 7

6,277 Please ans​

Answer 1

Step-by-step explanation:

Take the last digit of the number double it.

7 double of 7 is 14.

Then subtract the result from the rest of the number

627-14 = 613

If the resulting number is evenly divisible by 7, so is the original number.

613 ÷ 7 = 87.57

Which is not divisible by 7 so 6277 is also not divisible by 7.
