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.
