Infinity is just so big that by comparison, bigness itself looks really titchy.
Gigantic multiplied by colossal multiplied by staggeringly huge is the sort of concept we're trying to get across here. If infinity is to be anything at all, perhaps it is a number. But wait a minute. I shall tell you one answer. It certainly seems that this question should have an answer, and that its answer should be a number, but certainly not 3, or 5, or a million, or any other whole number.
