Sorry! I’ll try doing that instead. It’s just looks better in text. Again it can always be changed
Although I can see why you like it better visually in text, it can be used easier as a list.
Also, you should replace the 
block with
to make an empty list. Using the first method creates a one-item list where the item is nothing.
This is my take:
for gcf, use the () max () @<:> block and drag the common factor block onto the 3 vertical dots between the arrows on the right of the block.
btw, there is an else if block, no need for the nested if elses. click the arrow at the bottom of the normal if<>{ }@> block.
I made the block before I learned that from looking at other scripts. But thanks for the info
@da-ultimate-creater okay, thanks for the additional information!
