I have yyyym format in excel, I want previous month in the same format

So if my date is 201701, I want the next column as 201612(previous month) Also if my date is 201701, I want the quarter also as 201703 in another column. Thanks!
Month  Prev_Month  Quarter
201701 201612 201703
This is the output I want. Preferably in excel.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.


If your current month is in A1:

Previous Month = VALUE(TEXT(DATE(LEFT(A2,4),RIGHT(A2,2),0),"YYYYMM"))

Quarter = VALUE(TEXT(DATE(LEFT(A2,4),RIGHT(A2,2)+MOD(-MOD(RIGHT(A2,2),3)+3,3)+1,0),"YYYYMM"))

See attached.
