The answer depends on whether or not a is a factor of c.
What is the difference between basic notes and notes with numbers for piano?
A note with a number (like C4) represents a note (C) in a particular octave (4th). A note without a number represents that note in any octave, and could be played in any octave. In the example, C4 represents "Middle C", or the 4th C up from the lowest C on a grand piano - 4 octaves above C0. A4 is the standard notation for a frequency of 440Hz.

8 is a factor of 40
What is the difference between factors and prime factors?
A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
