Is there an algorithm for prime factorization?

Algorithm for Prime Factorization

The simplest algorithm to find the prime-factor is by repeatedly dividing the number with the prime factor until the number becomes 1. Thus 100 divided by 2 become 50. Now our number becomes 50. Thus 50 divided by 2 become 25.

How is prime algorithm calculated?

Algorithm to Find Prime Number

STEP 1: Take num as input. STEP 2: Initialize a variable temp to 1. STEP 3: Iterate a “for” loop from 2 to sqrt(num). STEP 4: If num is divisible by loop iterator, then update temp value to 0.

What is the prime factor method?

Prime factorisation is a method to find the prime factors of a given number, say a composite number. These factors are nothing but the prime numbers. A prime number is a number which has only two factors, i.e. 1 and the number itself. For example, 2 is a prime number which has two factors, 2 × 1.

What is the fastest prime factorization algorithm?

The fastest-known fully proven deterministic algorithm is the Pollard-Strassen method (Pomerance 1982; Hardy et al. 1990).
