What was the first illegal prime number?

The first illegal prime number, discovered by Phil Carmody in March 2001, is a 1401-digit prime whose hexadecimal representation encodes the gzipped source code for DeCSS (a DVD decryption program), making its distribution potentially illegal under laws like the Digital Millennium Copyright Act (DMCA). It's considered "illegal" because it's a prime number that, when interpreted in a specific way (as data), describes a tool that bypasses copyright protection, thus falling into a legal gray area or outright violation in some jurisdictions.

What is an illegal prime number?

An illegal prime is a prime number that represents information whose possession or distribution is forbidden in some legal jurisdiction. One of the first illegal primes was found in 2001.

Is 12345678910987654321 a prime number?

The number 12,345,678,910,987,654,321 is indeed prime. It consists of 20 digits and is really easy to remember: count to 10 and then count backward again until you get to 1. But it has been unclear whether other primes take the palindromic form of starting at 1, ascending to the number n and then descending again.

Why is 2027 a prime number?

2027 is a prime number because, by definition, it's a whole number greater than 1 that has only two factors: 1 and itself, meaning no other whole number can divide into it evenly. You can verify this by checking for divisors up to its square root (around 45), and you'll find no integer factors other than 1 and 2027, making it a foundational element in number theory and cryptography. 

What is the 10000000000000th prime number?

For example, entering either 1,000,000,000,000 or 1.0e12 will tell you ' The 1,000,000,000,000th prime is 29,996,224,275,833.

Is 170141183460469231731687303715884105727 a prime number?

Using this algorithm with hand computations on paper, Lucas showed in 1876 that the 39-digit number (2127 – 1) equals 170,141,183,460,469,231,731,687,303,715,884,105,727, and that value is prime. Also known as M127, this number remains the largest prime verified by hand computations.

Is 2099 prime?

Yes, 2099 is a prime number, meaning its only factors are 1 and itself (2099). It's notable as the 317th prime number and a "self prime year," according to Prime Curios!.
 

Is 1000000000000066600000000000001 a prime?

Due to the superstitious significance of the numbers it contains, the palindromic prime 1000000000000066600000000000001 is known as Belphegor's Prime, named after Belphegor, one of the seven princes of Hell.

How many primes exist?

By Euclid's theorem, there are an infinite number of prime numbers. Subsets of the prime numbers may be generated with various formulas for primes. The first 1,000 primes are listed below, followed by lists of notable types of prime numbers in alphabetical order, giving their respective first terms.

Why is 93 not a prime?

The number 93 is divisible by 1, 3, 31, 93. For a number to be classified as a prime number, it should have exactly two factors. Since 93 has more than two factors, i.e. 1, 3, 31, 93, it is not a prime number.

Why is 37 so special?

The number 37 is special due to its unique mathematical properties as a prime number (emirp, safe prime, sexy prime, etc.), its surprising frequency in "random" number choices (like in the secretary problem), its connection to repeating digits (37 x 3 = 111), and cultural/spiritual symbolism, making it a fascinating number in math, science, and belief systems.
 

Is 99194853094755497 prime?

For example, I found online that one Fibonacci Prime is term 83, which is provably prime and is known as 99194853094755497.

Are there fake primes?

A pseudoprime is a probable prime (an integer that shares a property common to all prime numbers) that is not actually prime. Pseudoprimes are classified according to which property of primes they satisfy. Some sources use the term pseudoprime to describe all probable primes, both composite numbers and actual primes.

Why is 52 an untouchable number?

52 is an "untouchable number" in mathematics because it's a positive integer that can never be the result of adding up the proper divisors (all divisors except the number itself) of any other positive integer, meaning no number "touches" 52 by having its divisors sum to it, unlike numbers like 6 (1+2+3) or 9 (1+3) which are sums of proper divisors. It's one of the early untouchable numbers, appearing after 2, 5, 88, 96, 120, and 124 in the sequence.
 

What is a prime number for idiots?

A prime number is a whole number larger than the number 1 that can be divided evenly only by itself and 1. The first and smallest prime number is the number 2. It's the only even prime number.

Are 2027 and 2029 prime?

The numbers after

The next prime number is 2,029, 2 numbers away. As a result, 2,027 and 2,029 are twin primes.

Why isn't 1 prime?

1 is not a prime number because it only has one factor (itself), while prime numbers must have exactly two distinct factors (1 and itself); crucially, including 1 as prime would break the Fundamental Theorem of Arithmetic, which states every integer has a unique prime factorization (e.g., 6 = 2×3, not 2×3×1×1×1...), making unique decomposition impossible. 

Are 2 and 3 twin primes?

(2,3) are not considered as twin primes, since there is no composite number in between them and the difference between the two primes is not equal to 2. Every prime pair other than (3,5) is in the form of (6n-1, 6n+1), where n is any natural number. The sum of each prime pair apart from (3,5) is divisible by 12.

What is 1 ➗ 0 and why?

As much as we would like to have an answer for "what's 1 divided by 0?" it's sadly impossible to have an answer. The reason, in short, is that whatever we may answer, we will then have to agree that that answer times 0 equals to 1, and that cannot be ​true, because anything times 0 is 0.

Is Belphegor a fallen angel?

Belphegor is a fallen angel who after falling from heaven now serves as the Demon Lord presiding over the sin of Sloth.

What is the sixth prime?

The sixth prime number is 13. A prime number is an integer greater than 1, whose only factors can be just 1 and itself, it must have only two positive factors. The first five prime numbers before 13 are 2, 3, 5, 7, and 11.
