I need to factorize large numbers (some of them have about 200 decimal digits). Wolfram alpha is a dead end and programming with python is not working for me too. Any suggestions?

Prime factorization is the process of breaking down a number into its prime factors, which are the building blocks of the number. Prime factors are prime numbers that can divide the original number without leaving a remainder.
Prime factorization is important for large numbers because it helps us to understand the factors that make up the number and to find the greatest common divisor or lowest common multiple of a set of numbers. It is also useful for simplifying fractions and solving certain mathematical problems.
The most common method for finding the prime factors of a large number is by using a factor tree. Start by dividing the number by its smallest prime factor and continue breaking down the resulting factors until all the factors are prime numbers. Another method is by using a prime factorization calculator or a prime factorization algorithm.
Prime factorization and prime decomposition are essentially the same process, but prime decomposition is often used to describe the process of breaking down a number into its prime factors without showing the steps or using a factor tree. Prime factorization, on the other hand, typically refers to showing the steps and using a factor tree.
Yes, you can use prime factorization to determine if a number is prime or composite. If a number has only two prime factors (itself and 1), then it is a prime number. If a number has more than two prime factors, then it is a composite number. This is because a prime number can only be divided by itself and 1 without leaving a remainder, while a composite number has multiple factors.
