How Is the Value of 4⋄ Calculated in This Math Problem?

[depathak15]

y$$\diamond$$ is defined for all positive integer values of y as the product of all positive odd factors of 3y. For example, 6$$\diamond$$= 1 x 3 x 9 = 27. What is the value of 4$$\diamond$$?


Answer: 3


I tried this question and i got it wrong. This question is on the Kaplan SAT Practice Test.
I want to know how they got the solution to this problem. Can you provide an explanation for this question?

Thank You for your time...

BTW, I do not know where to post this question, so I decided this would be the best place...

4$$\diamond$$ would be the product of all positive odd factors of 3(4) = 12...which would be 1 x 3 = 3.
