By:- Hit and trials
let the certain number is =X
apply the condition of we multiply by 7 product consist entirely of fives
X*7=5,55,555,5555,55555 or 555555
X= 5/7,55/7,555/7,5555/7,55555/7 or 55555.
so least value of such number is
===>(1)5/7= 0.714 ( in decimals)
===>(2)555555/7=79365 ( without decimals )
