The element factorization calculator will certainly take any kind of number and find its prime factors. Simply form the number into our tool and also in no time you"ll uncover the element factorization. To know the totality process, very first you must get acquainted with what is a element factor. Once you recognize that, us will relocate on come the difference in between prime factor and also prime factorization.

You are watching: What are the factors of 20

Below, you"ll discover all the answers, and also concise information about how to discover prime factorization and also what a variable tree is.

To know prime factorization, we need to start native the beginning - what is a element number? A prime numbers are numbers whose only components are one and itself - in various other words, the can"t be created by multiplying two smaller natural numbers. A an essential point to note is that the two factors must be different, for this reason 1 is no a prime number since both components of 1 room the same. Because that example, 5 is a element number due to the fact that the only factors of 5 space 1 and also 5. 6 is not a element as, except 1 and also 6, other determinants exist - 2 and 3.

There space infinitely many primes and there"s no simple formula to determine whether a number is a element or not. That"s why this prime factorization calculator is together a great, multi-purpose device - you have the right to use it as a prime number calculator as well!

## What is a element factor?

Prime factors are determinants of a number that space themselves prime numbers. Because that example, suppose we desire to uncover the factors of 20, the is, we want to recognize what entirety numbers multiply to offer you 20. We recognize that 1 * 20 = 20, 2 * 10 = 20 and also 4 * 5 = 20. But notice that 20, 10 and 4 room not prime factors. The just prime determinants of 20 space 2 and also 5. Friend can also get these determinants with the use of our factor calculator.

## What is element factorization?

Prime administrate is as soon as we rest a number down into factors that are just prime numbers. If we look in ~ the above example with 20, the components are 1, 2, 4, 5, 10, 20. The best place to start is to uncover at least one initial aspect that is prime. Because 5 is prime, we deserve to start through 4 * 5. Notice that 4 is not prime, so we break 4 down into 2 * 2. Because 2 is prime, the prime factorization of 20 is 2 * 2 * 5. Go ahead and check this result with our element factorization calculator.

## How to find prime factorization? A aspect tree method

We"ll present you step by step how to find prime factorization. We"ll use the element tree diagram, an easy means to malfunction a number right into its element factors. Space you ready?

Take a number. There"s no point in picking a element number, together the element factorization will finish at this point. Let"s select 36.Factor that into any two numbers, element or not. You might want to take the most basic splits, e.g., if your number is even, break-up it into 2 and the various other number. 36 is even so the we deserve to write it as 2 * 18.Start creating the factor tree. Attract two branches splitting down from your original number.

Factor the next line. If your number is a prime, leave it together it is. If it"s no a element number, repeat step 2.
Repeat step 4 till you"re left with just prime numbers.
Write down the last prime factorization and prime factors.
Take all the "leaves" of your element tree and multiply castle together:

36 = 2 * 2 * 3 * 3

That"s how we uncover prime factorization!

The prime factors the our original number 36 are 2 and also 3. The very same prime factor may occur much more than once, which is precisely what occurred in our instance - both element numbers show up twice in the element factorization. We have the right to then express that as:

36 = 2² * 3²

Of course, friend should acquire the same result with a different factor tree splits, as e.g. Here:

## Greatest typical Factor

Prime administer is the first step in recognize the greatest usual factor - the greatest element of two or more numbers. The GCF is especially useful for simple fractions and solving equations utilizing polynomials. Because that example, the greatest usual factor between 6 and 20 is 2: element factorization of the first number is 6 = 2 * 3, the last may be expressed together 20 = 5 * 2 * 2, and also the only number which shows up in both element factorizations is 2, indeed. If you desire to calculate greatest usual factor in a snap, use our greatest typical factor calculator.

## Least usual Multiple

The the element factorization calculator is also useful in detect the least typical multiple (LCM). The LCM is necessary when including fractions with different denominators. The least common multiple is acquired when you multiply the higher powers of all factors between the 2 numbers. For example, the least common multiple in between 6 and also 20 is (2 * 2 * 3 * 5) = 60. The LCM may be uncovered by hand or through use that the least typical multiple calculator.
