Struct Factorization 

pub struct Factorization;

Prime Factorization

This struct is used to factor large numbers and return their largest prime factor

use num_primes::{Generator,Factorization};
 
fn main() {
    // Generates New Unsighed Integer of 64 bits
    let uint = Generator::new_uint(64);
    // Prime Factorization    
    let prime_factor = Factorization::prime_factor(uint);
 
    match prime_factor {
        Some(x) => println!("Largest Prime Factor: {}",x),
        None => println!("No Prime Factors Found"),
    }
}

Implementations

impl Factorization

pub fn prime_factor(n: BigUint) -> Option<BigUint>

Prime Factorization

This is a method of factoring the largest prime factors of large numbers. It is slow and should not be relied on. It can easily factor 32-bit numbers and sometimes 64-bit.

It returns as a Option<BigUint> type

use num_primes::{Generator,Factorization};
 
fn main() {
    // Generates New Unsighed Integer of 32 bits
    let uint = Generator::new_uint(32);
    // Prime Factorization    
    let factor = Factorization::prime_factor(uint);
 
    match factor {
        Some(factor) => println!("Largest Prime Factor: {}",factor),
        None => println!("No Prime Factors Found"),
    }
}
