Using a factor tree: Procedure: Find 2 factors of the number; Look at the 2 factors and determine if at least one of them is not prime; If it is not a prime factor it; Repeat this process until all factors are prime. See how to factor the number 72: 72 / \ 2 36 / \ 2 18...
None of them is a factor of 1601, so 1601 is prime. There is an important quantity in number theory, referred to as Euler’s totient function and denoted by φ(n), defined as the number of positive integers less than n and relatively prime to n. By convention, φ(1)=1. For ...
One method of prime factorization is called the trial division method. To use this method to find all the prime factors of a number, sayx, for example, start by dividingxby any prime number. If the resulting value is not a whole number, then that prime number is not a prime factor of...

The greatest common divisors of the sides contained therein are the factors of the semi-prime. We then prove that to factor a semi-prime, it is sufficient that only one of these Pythagorean quadruples be known. We provide the algorithm of our proposed semi-prime factorization method, ...
Conferring to the definition of the prime number, which states that a number should have exactly two factors for it to be considered a prime number. But, number 1 has one and only one factor which is 1 itself. Thus, 1 is not considered a Prime number. Examples: 2, 3, 5, 7, 11,...
