function factor theNumber
    put empty into theFactors
    repeat with theDivisor = 2 to the sqrt of theNumber
        repeat while theNumber mod theDivisor is zero
            put theDivisor & "*" after theFactors
            divide theNumber by theDivisor
        end repeat
        if theNumber is one then exit repeat
    end repeat
    if theNumber is not one
    then put theNumber after theFactors
    else delete last char of theFactors
    return theFactors
end factor

repeat
    ask "Number to factor:"
    if it is empty or the result is "Cancel" then exit repeat
    else put factor(it)
end repeat
