Is it a geometric sequence or not? Well, last time I asked for an arithmetic sequence, now comes the geometric sequence
Challenge
In this challenge, the input will be an unordered set of numbers and the program should be able to tell if the set of numbers is a Geometric Sequence.
Input

The input will be a set separated by ,(comma).

Output

The Output can be a Boolean (True or False), or a number (1 for True, 0 for False).

Test cases
In: 1,3,9
Out: True

In: 1,4,16
Out: 1

In: 2,6,14
Out: 0

In: 2,8,4
Out: True

In: 4,6,9
Out: 1

Rules

This is code-golf, so the shortest code by bytes wins.
The minimum length of the input set would be 3 elements.

Best of Luck

Thanks to fireflame241 for pointing out a mistake
How it works
Ṣ÷ƝE - Main monadic link, takes an array as input
     - e.g                            A = [2, 8, 4] or   A = [2, 6, 14]
Ṣ    - Sort                               [2, 4, 8]          [2, 6, 14]
  Ɲ  - Over overlapping pairs [x, y]...   [[2, 4], [4, 8]]   [[2, 6], [6, 14]]
 ÷   - ...divide x by y?                  [0.5, 0.5]         [0.33, 0.43]
   E - Is the list all the same?          1                  0
