My 200th Video - Counting Zeros and Finding a Digit from 200! (factorial)

0:00 Video Starts 0:30 PART 1. The Number of Trailing Zeros of 200! 3:07 PART 2. The Rightmost Nonzero Digit of 200! - An Introduction 4:03 The Rightmost Nonzero Digit of 200!, METHOD 1 13:19 The Rightmost Nonzero Digit of 200!, METHOD 2 This is my 200th official video of this channel! Many thanks to my viewers who watch my videos and thereby motivate me to make some more. In this video, I am going to find the number of trailing zeros and the rightmost nonzero digit of 200! (200 factorial). By doing so, we can learn many fascinating things such as the correlation between number of zeros and certain prime factors, interesting properties related to rightmost nonzero digits, and a neat theorem about factorials and rightmost nonzero digits. *Throughout the video, I used the term "TAILing zeros," but the correct term that is being widely used is "TRAILing zeros." This is one of those instances where I had to learn the terminology in English because it is not my first language and ended up getting it wrong. Sorry if this caused any confusion.
