KPop Group names with a Number

Just what is this strange fascination of KPop Entertainment Corporates/Agencies naming or forming groups with a number associated with it. 

Why is it? You can read this at: LABBRAND - Easy Western Recognition, Group Size/Sentiment, Marketing Strategy... you name it ... it can be anything!

Here I have dug up close to 100 such groups/units/bands/artists/duos below. Some are World Famous, Some Active, Some Disbanded, Some Folded up after announcement, Some barely made it out of the blocks. Yepp, they are all in here. And to just keep it simple the focus is on Group Names and members associated with the group (in totality). 

Just didn't want to elaborate further. These number are either mentioned as a Number itself or simply put in English starting with 1, 2, 4, 5, 6, 7, 8, 9, 10, 14, 15, 16, 17, 20, 21, 24, 66, 69 100, 127, 707 being some of the numbers in use.
