Factor in mathematics is a number that can divide another number precisely leaving no remainder. In basic words, factors are whole numbers that can isolate a number more noteworthy than it precisely and equitably without a remaining portion.

Factors are numbers and are never fractions or decimals. They can be both positive and negative numbers. Just two factors are conceivable on account of indivisible numbers while for composite numbers there are two factors.

## Factors Of 18 – Definition and Prime Factorization

The factor is a simple however extremely valuable subject. Such a significant numerical device is utilized in all levels of maths beginning from grade school level to higher high-level levels.

It is utilized in any remaining science and numerous expressions subjects too. A significant tool for estimations associated with everyday life. Likewise, by the term factors of 18, we mean that a multitude of numbers can partition the number 18 equitably with a remainder of zero.

### Factors of 18

Factors of 18 are the results of such numbers which totally partition the given number 18. Factors of a given number have two values; they can be either negative or positive numbers. By increasing the factors of a number we get the first number. For instance, 1, 2, 3, 4, 6, 12 are the factors of 12. Thus we have 4 x 3 = 12 or 6 x 2 = 12 as the pair factors of 12.

In this article, we will concentrate on the factors of 18, what are the factors of 18, what is the prime factorization of 18, the factor tree of 18, all factors of 18, and models. Factor sets of the number 18 are the sets of the entire numbers which could be either sure or negative but not a small portion or decimal number. Factorization is the normal technique to track down the factors of 18.

### Definition

The factors of a number are characterized as the numbers which give the first number on increasing the two factors. The factors can be either sure or negative whole numbers. Factors of 18 are the whole numbers that can equally isolate the given number 18. Presently let us concentrate on the best way to compute all factors of 18.

### What are the Factors of 18?

As per the meaning of factors of 18, we realize that factors of 18 are the positive or negative numbers that partition the number 18 totally. So let us essentially partition the number 18 by each number which totally isolates 18 in ascending order 18.

- 18 ÷ 1 = 18
- 18 ÷ 2 = 9
- 18 ÷ 3 = 6
- 18 ÷ 4 = not divides totally
- 18 ÷ 5 = not divides totally
- 18 ÷ 6 = 3
- 18 ÷ 7 = not divides totally
- 18 ÷ 8 = not divides totally
- 18 ÷ 9 = 2
- 18 ÷18 = 1

So, all factors of 18: 1, 2, 3, 6, 9, and 18.

We realize that factors additionally incorporate negative whole numbers consequently we can likewise have,

a list of negative factors of 18: – 1, – 2, – 3, – 6, – 9 and – 18.

### All Factors of 18 Can be Listed as Follows

- Positive Factors of 18 1, 2, 3, 6, 9 and 18
- Negative Factors of 18 -1, – 2, – 3, – 6, – 9 and – 18.

Subsequently, 18 has a sum of 6 positive factors and 6 negative factors.

### All Factor Pairs of 18

All Component Sets of 18 are mixes of two factors that when increased together give 18.

List of all the positive pair factors of 18

- 1 x 18 = 18; match factors are(1, 18)
- 3 x 6 = 18; match factors are(3, 6)
- 2 x 9 = 18; match factors are(2, 9)

So (1, 18), (3, 6), and ( 2, 9), are the positive pair factors of 18

As we realize that Factors of 18 incorporate negative whole numbers as well.

### Rundown of all the negative pair factors of 18

- -1 x – 18 = 18
- -3 x – 6 = 18
- -2 x – 9 = 18

So (- 1, – 18), (- 3, – 6) and ( – 2, – 9) are the negative pair factors of 18

Presently we will concentrate on what is the prime factorization of 18.

### What is the Prime Factorization of 18?

As indicated by the prime factor definition, we realize that the excellent element of a number is the result of the multitude of factors that are prime, which is a number that divides without anyone else and only one. Subsequently, we can list the superb factors from the list of factors 18.

Or the alternative way of finding the prime factorization of 18 is by prime factorization or by factor tree of 18.

Presently let us concentrate on the prime factors of 18 by division method.

### Prime Factors of 18 by Division Method

To compute the great factors of 18 by the division technique, first, take the least prime number which is 2. Divide it by 2 until it is totally divided by 2. If at a point it isn’t distinguishable by 2 take the following least indivisible number which is 3. Play out similar advances and push ahead, till we get 1, as the quotient. Here is the stepwise strategy to ascertain the superb factors of 18

**Step 1: Divide 18 with 2**

18 ÷ 2 = 9

**Step 2: Divide 9 with 2**

9 ÷ 2 = not divisible

**Step 3: So take one more prime number 3 Divide with 3**

9 ÷ 3 = 3

**Step 4: Presently again divide 3 by 3**

3 ÷ 3 = 1

We get the quotient 1.

From the above steps, we get an excellent element of 18 as 2 x 3 x 3 = 2 x 32

Here is the factor tree of 18.

### FAQ on Factors of 18

**What do you mean by a Factor Tree?**

A factor tree is a simple graph to decide the factors of a number, typically a large number. It resembles a tree with each part of the tree being parted into the factors of the number consequently splitting a large number into its factors. The splitting of branches closes just when the element toward the finish of the branch is an indivisible number which can additionally be parted into just two factors of 1 and the actual number.

The treetop is the number whose factors are to be found. The principal parts of the tree will incorporate one least indivisible number which can be a component of the number and the rest composite number which can be additionally requested to factors until at last, just the indivisible numbers stay toward the finish of the tree limbs and the splitting stops.
