New largest prime discovered 2^{74\,207\,281}-1

New largest prime discovered 

\Huge2^{74\,207\,281}-1

Recall a prime number is one which is only divisible by itself and 1 and the smallest prime numbers are 2,3,5,7,11,13,17,....

The new largest prime number has got over 22 million digits! that's right!
The number 1\,000\,000 has 7 digits! Can you imagine a number with 22 million digits!
A book may have say 2000 characters to a page, so that's about 22\,000\,000\div 2000=11\,000 pages just to write out the number long hand!
