# The Significance and Challenges of Prime Numbers in Mathematics

TLDR Prime numbers, which are only divisible by themselves and one, are the fundamental building blocks of mathematics and play a central role in various mathematical problems. The distribution and determination of prime numbers, including the search for the largest known prime number, pose significant challenges in mathematics, such as the unsolved Riemann Hypothesis. Additionally, prime numbers have practical applications in fields like cryptography and cryptocurrencies.

### Timestamped Summary

00:00
Prime numbers are the building blocks of mathematics and remain at the center of some of the most puzzling problems in the field.

01:41
A prime number is a number that is only divisible by itself and one, and there are an infinite number of prime numbers.

03:21
The Fundamental Theorem of Arithmetic states that any number can be broken down into component prime numbers, and prime numbers are considered to be the building blocks of numbers.

04:55
The distribution of prime numbers and the difficulty in predicting or determining if a number is prime is a major unsolved problem in mathematics known as the Riemann Hypothesis.

06:29
Mersenne primes are a special type of prime number that can be checked relatively quickly, making them a popular choice for finding the largest known prime number.

08:03
The largest known prime number has over 24 million digits and can be found online, and there are ways to test if a number is prime using probability.

09:45
Prime numbers have important practical uses in cryptography, including public key cryptography, and are also central to many cryptocurrencies.
