$(b)65302419 = 65,302,419$
$\therefore $Number names – Sixty-five million three hundred and two thousand four hundred and nineteen.
$(c)577627389 = 577,627,389$
$\therefore $Number names – Five hundred seventy-seven million six hundred twenty-seven thousand three hundred and eighty-nine.
$(d)4529162 = 4,529,162$
$\therefore $Number names – Four million five hundred twenty-nine thousand one hundred and sixty-two.
