What is a Gaussian factor?
The Gaussian integers are complex numbers of the form a + b i, where both a and b are integer numbers and i is the square root of -1. The factorization is unique, if we do not consider the order of the factors and associated primes. This issue disappears by selecting prime numbers a + b i such that a >= | b |.
How many factors does a googol have?
There are 14 numbers that have no known factors. See the related table including known prime factors of numbers of the form googolplex + 10Exp, where 0 ≤ Exp ≤ 9….Factors of 1000 numbers starting from googolplex.
| n | Prime factors known |

What are the factors of googolplex?
A googolplex is is ten raised to the power of a googol, i.e., 10(10100) 10 ( 10 100 ) .
Is 3 a Gaussian prime number?
Note that there are rational primes which are not Gaussian primes. A simple example is the rational prime 5, which is factored as 5=(2+i)(2−i) in the table, and therefore not a Gaussian prime….Factorizations.

| 13 | 3+2i 2+3i | (p) (p) |
| 16 | 4 | −(1+i)4 |

| 18 | 3+3i | (1+i)·3 |
Is 13 a Gaussian prime?
These numbers can’t be expressed as the sum of two squares. All of the numbers congruent to 1 mod 4 which is also 4k+1 are 1,5,13,17,29,37, and 41, so these numbers can be expressed as the sum of squares and can be expressed as Gaussian Integers as well.
What is prime number and prime factor?
Prime factorization is a way of expressing a number as a product of its prime factors. A prime number is a number that has exactly two factors, 1 and the number itself. For example, if we take the number 30. We know that 30 = 5 × 6, but 6 is not a prime number.
How do you find prime factors?
The steps for calculating the prime factors of a number is similar to the process of finding the factors of any number.
- Start dividing the number by the smallest prime number i.e., 2, followed by 3, 5, and so on to find the smallest prime factor of the number.
- Again, divide the quotient by the smallest prime number.
How large is a googol?
A googol is a 1 followed by 100 zeros (or 10100 ). It was given its whimsical name in 1937 by mathematician Edward Kasner’s young nephew, and became famous when an internet search engine, wanting to suggest that it could process a huge amount of data, named itself Google.
Is googol bigger than infinity?
Almost inevitably, at this point someone proffers an even bigger number, “googolplex.” It is true that the word “googolplex” was coined to mean a one followed by a googol zeros. It’s way bigger than a measly googol! True enough, but there is nothing as large as infinity either: infinity is not a number.
How big is Graham’s number?
Graham’s number is bigger the number of atoms in the observable Universe, which is thought to be between 1078 and 1082. It’s bigger than the 48th Mersenne prime, 257,885,161-1, the biggest prime number we know, which has an impressive 17,425,170 digits.
