Prime number factorization calculator

Prime numbers are natural numbers positive whole numbers that sometimes include 0 in certain definitions that are greater than 1, that cannot be formed by multiplying two smaller numbers. An example of a prime number is 7, since it can only be formed by multiplying the numbers 1 and 7. Other examples include 2, 3, 5, 11, etc. Numbers that can be formed with two other natural numbers, that are greater than 1, are called composite numbers. Examples of this include numbers like, 4, 6, 9, etc. Prime numbers are widely used in number theory due to the fundamental theorem of arithmetic. This theorem states that natural numbers greater than 1 are either prime, or can be factored as a product of prime numbers. As an example, the number 60 can be factored into a product of prime numbers as follows:. Prime factorization is the decomposition of a composite number into a product of prime numbers. There are many factoring algorithms, some more complicated than others. One method for finding the prime factors of a composite number is trial division. Trial division is one of the more basic algorithms, though it is highly tedious. It involves testing each integer by dividing the composite number in question by the integer, and determining if, and how many times, the integer can divide the number evenly. As a simple example, below is the prime factorization of using trial division:.

If you find any error or you have a comment, please fill in the form. This enables us to find relations about twice as fast as the non large prime variation. This is also known as prime decomposition.

The calculator does not work with Javascript disabled. Please check your browser settings. Type one numerical expression or loop per line. The program uses local storage to remember the progress of factorization, so you can complete the factorization of a large number in several sessions. Your computer will remember the state of the factorization, so you only have to reload this page. Since all calculations are performed in your computer, you can disconnect it from the internet while the factorization is in progress.

Use this prime numbers calculator to find all prime factors of a given integer number up to 10 trillion. This calculator presents:. For the first prime numbers, this calculator indicates the index of the prime number. The limit on the input number to factor is less than 10,,,, less than 10 trillion or a maximum of 13 digits. Prime factorization or integer factorization of a number is breaking a number down into the set of prime numbers which multiply together to result in the original number. This is also known as prime decomposition. We cover two methods of prime factorization: find primes by trial division, and use primes to create a prime factors tree. Say you want to find the prime factors of using trial division. Start by testing each integer to see if and how often it divides and the subsequent quotients evenly. The resulting set of factors will be prime since, for example, when 2 is exhausted all multiples of 2 are also exhausted.

Prime number factorization calculator

The prime factorization calculator finds a number's prime factors. The calculator demonstrates the prime factors tree and all factors of the number. This online factorization calculator finds all prime factors of the input number. The calculator demonstrates prime factors in the general form, as well as in the exponential form and the CSV format. Additionally, this factorization calculator can create a prime factor tree and find all not just prime factors of the given number. To use this calculator to find prime factors of a number, enter the given number and press "Calculate. You also have an option of creating a factorization tree and the possibility of finding all factors of the given number. Both of these options can be chosen by ticking a corresponding box.

Since is no longer divisible by 2, test the next integers. Sqrt n : Integer part of the square root of the argument. Weisstein, Eric W. Using NumDigits n,r : Number of digits of n in base r. A Smith number, according to Wikipedia, is a composite number for which, in a given base in base 10 by default , the sum of its digits is equal to the sum of the digits in its prime factorization. This page was last changed on: 09 July In this example, 6 and 5 are the factors of To print a percent sign, you have to write two percent signs, and a quote is represented by a percent sign followed by a quote. This enables us to find relations about twice as fast as the non large prime variation. F n : Fibonacci number F n from the sequence 0, 1, 1, 2, 3, 5, 8, 13, 21, etc. With this input box, you can determine the number of digits in a group.

Auto Calculate works for numbers. See all numbers factored to date.

New curve number or factor:. The execution time depends on the magnitude of the second-largest prime factor and on your computer's speed. To print a percent sign, you have to write two percent signs, and a quote is represented by a percent sign followed by a quote. This number must not be a perfect power. In multiplication, factors are the integers that are multiplied together to find other integers. SumDivs n : Sum of all positive divisors of n. Using Weisstein, Eric W.

This theorem states that natural numbers greater than 1 are either prime, or can be factored as a product of prime numbers. Prime factorization or integer factorization of a number is breaking a number down into the set of prime numbers which multiply together to result in the original number.
