How many cores in one million?

Could you please enlighten me on a matter of mathematical curiosity? I'm wondering, if we were to consider the vast quantity of one million, how many individual cores would that equate to? This question piques my interest as I strive to grasp the magnitude of such a large number in the context of smaller, more tangible units like cores. Would you be able to assist me in understanding this concept, possibly by breaking it down into smaller, more manageable chunks? Thank you for your time and assistance in this matter.
