Venus is in the news! I looked up this well-regarded paper by A. S. Konopliv, W. B. Banerdt, and W. L. Sjogren

They list values for GM (see attached picture), such as

so in principle calculating M should be trivial. The problem is I am orders of magnitude off from the actual value. I thought perhaps they were using cgs units, but that gives a value for M that is 15 orders of magnitude off. Clearly, I'm missing something. I looked through the paper and couldn't find anything that clarified the situation. Anyone know the units they are using or what I am missing? Thanks in advance.

Edit: Just to clarify, this is NOT for homework or any school related activity. Simply my own understanding.
