The product of a whole number with a whole number is a whole number. A whole number is an integer ( a counting number).
The product of a whole number and another whole number is a whole number.
Greatest whole number is 259999.
The greatest whole number is 277300.
There is no greatest whole number. If x were the greatest whole number then what about x+1? It would be greater than x and it would be a whole number!
The answer depends on product of a whole number with WHAT?
