The factors of 20 space all the confident and an unfavorable integers which offer you the an outcome as number 20 once you multiply 2 numbers together. The element pairs of 20 space the whole numbers that can be either optimistic or an unfavorable but cannot be a portion or a decimal number. To find all determinants of 20, you have the right to use the prime factorization the 20 method.

In the element factorization method, you require to first consider the two numbers 1 and also 20 together the factors and then continue to uncover the various other pair of multiples that 20 that would give you the outcomes as an original number. For knowledge this technique in a far better way, read the article below for finding the components of 20 in pairs. Also, friend will find the method to find the prime factors of 20 by using the department method.

The factor pairs of 20 are the combine of two determinants which as soon as multiplied together amounts to to the number 20. Given below are every the positive variable pairs that 20 and all the negative factor pairs of 20.

Factor bag of 20


1 x 20 = 20

2 x 10 = 20

4 x 5 = 20

5 x 4 = 20

10 x 2 = 20

20 x 1 = 20


The determinants of 20 consists of an adverse pairs too because multiplying two negative numbers gives you a confident integer. Hence, you have the right to simply placed a minus sign in prior of every the numbers of the element pairs of 20.


-1 x -20 = 20

-2 x -10 = 20

-4 x -5 = 20

-5 x -4 = 20

-10 x -2 = 20

-20 x -1 = 20

How to discover the determinants of 20?

To discover all components of 20, follow the complying with steps:

The first step is composing down the number 20.

Then, find the 2 numbers such that they provide the an outcome as 20 as soon as you multiply them together. For example, 2 and 10. Multiplying them offers you 2 × 10 = 20.

You would understand that 2 is a prime number and also has only two factors, the is, 1 and the number itself. Hence, you can not factorize 2 further because 2 x 1 = 2.

However, 10 is a composite number and also not a element number. Hence, you deserve to factorize it more as 10 = 2 × 5 × 1.

Therefore, the administrate of 20 deserve to be created as:

20 = 2 × 2 × 5 × 1

Finally, you need to write down all the unique numbers that you can obtain from the number 20. Law so you get,

20 = 2 × 2 × 5 × 1

Hence, every the factors of 20 space 1, 2, 4, 5, 10, and 20.

Prime administrate of 20

Since the number 20 is a composite number, it consists of prime factors. Now, let us find the prime determinants of 20 using the prime factorization method.

The first step is splitting the number 20 through the smallest prime factor, i beg your pardon is 2 in this case.

Doing so, girlfriend get, 20 ÷ 2 = 10

Now, again, division the number 10 by 2 since 10 is a composite number and can be more divided.

Diving 10 by 2, friend get, 10÷ 2 = 5

Now, if you divide 5 through 2 friend would gain a fountain number, and that can not be a factor.

So, the next step is to proceed with the next prime numbers which is 5.

Since 5 is also a element number and cannot be split further, you divide it through the number itself.

Dividing the number 5 by itself provides you 5 ÷ 5 = 1

Now, you have received 1 at the end of the department process and also it is not feasible to continue further.
