Answer: Apparent magnitude.
Explanation: The absolute magnitude scale is how the luminosity (or true brightness) is measured. The luminosity depends on the temperature, size, spectra. The apparent magnitude is the brightness of the star<em> as it appears from Earth. </em>
A least common multiple the lowest common factor that the two numbers have in common. Hope this helps. :)
Answer:
