Factors that 18 are the numbers that offer the original number 18 when multiplied together in pairs. Basically, the components are the numbers that division the original number completely. The pair factor of 18 is a pair of number on multiplication, causing the initial number. The pair element of 18 deserve to be positive and negative, however it can not be a decimal or fraction. Because that example, the pair aspect of 18 is written as (1, 18) or (-1, -18). If us multiply a pair of an adverse numbers, such together multiplying -1 and -18, results in an initial number 18. In this article, we are going to discover what room the determinants of 18, pair factors and also the prime factors of 18 making use of the prime factorization method with plenty of solved examples.

What room the components of 18?

The components of 18 space the numbers that divide 18 fully without leave a remainder value. In various other words, the number which space multiplied together bring about the number 18 are the determinants of 18. Together 18 is an also composite number, it has an ext factors various other than 1 and 18. Hence, the components of 18 room 1, 2, 3, 6, 9 and 18, and also its an adverse factors room -1, -2, -3, -6, -9 and -18.


Factors that 18: 1, 2, 3, 6, 9 and also 18.

Prime administer of 18: 2 × 3 × 3 or 2 × 32.


Pair components of 18

The numbers which are multiplied together leading to 18 is called the pair element of 18. As discussed above, the pair determinants of 18 can be confident or negative. Thus, the positive and negative pair factors of 18 are offered below:

Positive Pair components of 18:


Positive determinants of 18

Positive Pair determinants of 18

1 × 18

(1, 18)

2 × 9

(2, 9)

3 × 6

(3, 6)


Negative Pair factor of 18:


Negative factors of 18

Negative Pair components of 18

-1 × -18

(-1, -18)

-2 × -9

(-2, -9)

-3 × -6

(-3, -6)


Hence, the hopeful pair components of 18 space (1, 18), (2, 9) and also (3, 6). Similarly, the negative pair factors of 18 are (-1, -18), (-2, -9), (-3, -6).

Factors the 18 by division Method

In the division method, the determinants of 18 are found by splitting 18 by various integers. If the integers division 18 exactly and leave the remainder zero, climate those integers room the factors of 18. Now, let united state start separating 18 by 1 and also proceed through the different integers.

18/1 = 18 (Factor is 1 and Remainder is 0)18/2 = 9 (Factor is 2 and also Remainder is 0)18/3 = 6 (Factor is 3 and also Remainder is 0)18/6 = 3 (Factor is 6 and Remainder is 0)18/9 = 2 (Factor is 9 and Remainder is 0)18/18 = 1 (Factor is 18 and also Remainder is 0)

If we divide 18 by any kind of numbers other than 1, 2, 3, 6, 9 and 18, it leaves a remainder. Thus, the components of 18 are 1, 2, 3, 6, 9 and 18.

Prime administrate of 18

The number 18 is a composite number. Currently let us uncover the prime determinants of it.

The an initial step is to divide the number 18 v the smallest prime factor,i.e. 2.

18 ÷ 2 = 9

Now, check whether 9 can be further divided by 2 or not.

9 ÷ 2 = 4.5

It offers a fractional value. However the factors should it is in a entirety number.

Therefore, we will move to the following prime number, i.e. 3.

Now, division 9 by 3.

9 ÷ 3 = 3

Again division 3 through 3.

3 ÷ 3 = 1

Examples

Example 1:

Find the common factors that 18 and also 17.

Solution:

The determinants of 18 room 1, 2, 3, 6, 9 and also 18.

The determinants of 17 are 1 and also 17.

As 17 is a prime number, the common factor of 18 and also 17 is 1.

Example 2:

Find the common factors that 18 and 19.

Solution:

Factors that 18 = 1, 2, 3, 6, 9 and also 18.

Factors the 19 = 1 and also 19.

The common factor of 18 and also 19 is 1, together 19 is a prime number.

Example 3:

Find the usual factors that 18 and 9.

Solution:

The factors of 18 room 1, 2, 3, 6, 9 and also 18.

The components of 9 room 1, 3 and 9.

Therefore, the common factors the 18 and also 9 are 1, 3 and also 9.
