Dividing a repeating 6-digit number by 15873
Select a repeating 6-digit number .
The answer is 7 times the first digit of the number!
Example:
777777 / 15873 = 7 x 7 = 49.
555555 / 15873 = 7 x 5 = 35.
999999 / 15873 = 7 x 9 = 63.
Not very demanding mental math, but good for a quick challenge or two.
