# Factors of 252: Prime Factorization, Methods, Tree, and Examples

The**factors of 252**are the set of natural numbers which give 252 when multiplied by one another. The two numbers undergoing multiplication constitute a

**factor pair.**The factors of 252 can also be defined as the set of natural numbers that make the number 252 completely divisible upon them. The only condition is that such numbers are bound to leave zero as the remainder and a whole number quotient to be labeled as

**“factors.”**The number 252 is an

**even composite number,**which indicates that this number will have more than two factors. These factors can be determined through the

**division method.**If you want to search for specific factors, say prime factors, then the methods are the

**prime factorization**and the

**factor tree**methods. In this article, we will conduct a detailed evaluation of these multiple methods for determining the factors of 252. We will also solve some examples involving these factors for better understanding.

## What Are the Factors of 252?

**The factors of 252 are 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, and 252. These natural numbers make 252 completely divisible upon them.**The number 252 has 18 factors in total, and these 18 factors can be evenly split into 9-factor pairs – positive and negative.

## How To Calculate the Factors of 252?

You can calculate the factors of 252 by using the**division method**. As mentioned above, the number 252 is even composite, so it will have multiple factors, 18 precisely.The division method is the simplest method for determining all these 18 factors. The division method has a simple rule – if the remainder is zero and a quotient is not a decimal number, then it’s a factor.As the general rule of factors, the number 1 and the

**number 252**already act as the smallest and largest factors, respectively. Still, since 252 is an even number, the number 2 will also be one of its factors.Given below is the demonstration of the division method for determining all these factors:\[ \frac{252}{1} = 252 \]\[ \frac{252}{2} = 126 \]\[ \frac{252}{3} = 84 \]\[ \frac{252}{4} = 63 \]\[ \frac{252}{6} = 42 \]\[ \frac{252}{7} = 36 \]\[ \frac{252}{9} = 28 \]\[ \frac{252}{12} = 21 \]\[ \frac{252}{14} = 18 \]\[ \frac{252}{18} = 14 \]\[ \frac{252}{21} = 12 \]\[ \frac{252}{28 } =9 \]\[ \frac{252}{36} = 7 \]\[ \frac{252}{42} = 6 \]\[ \frac{252}{63} = 4 \]\[ \frac{252}{84} = 3 \]\[ \frac{252}{126} = 2 \]\[ \frac{252}{252} = 1 \]Therefore, the complete list of factors of 252 is:

**Factors of 252: 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, and 252**As the number 252 is a natural number and the factor this number has also been set of natural numbers, two possible integers exist – one positive and the other negative. So in the way, negative factors of 252 can also exist, which are the same as the positive ones except with a negative sign.The negative factors of 252 are:

**Negative Factors of 252: -1, -2, -3, -4, -6, -7, -9, -12, -14, -18, -21, -28, -36, -42, -63, -84, -126, and -252**

## Factors of 252 by Prime Factorization

**Prime factorization**is the technique used to determine specific factors of a number. These particular factors are known as

**prime factors**. The prime factors are the numbers included in the factor list of a number and are prime numbers.The prime factorization technique is based on the mathematical operation of division in which only the prime numbers can occupy the place of divisors. These prime numbers carry out the division. The division through prime numbers is carried out until the last step, indicating that only the number 1 should be reminded at the end as the result of the division.The prime factorization for the number 252 is shown below:

**252 $\div$ 2 = 126**

**126 $\div$ 2 = 63 **

**63 $\div$ 3 = 21**

**21 $\div$ 3 = 7**

**7 $\div$ 7 = 1**

**Prime Factorization of 252 = 2 x 2 x 3 x 3 x 7**

**Prime Factorization of 252 = $2^{2}$ x $3^{2}$ x 7**

**Prime Factors of 252 = 2, 3, and 7**

## Factor Tree of 252

Like the**prime factorization**, the factor tree is also used to determine a number’s prime factors. The factor tree represents the prime factors in a visual manner through a tree-like structure.The

**factor tree**consists of two branches that originate from a number. The factor tree always requires one of these branches to hold a prime number. The other branch has the number which is subjected to division.The division of numbers continues until the factor tree only holds

**prime numbers**at both branches.The factor tree for the number 252 is shown below:

## Factors of 252 in Pairs

The factors of 252 also have the tendency to exist in the form of pairs known as**factor pairs.**One factor pair will comprise two numbers that will give the original number as the result when they are multiplied by each other.The requirement for the factor pair is that both numbers must have the same sign. The number 252 has 18 factors, meaning that this number will have

**9-factor pairs.**These are given below:

**1 x 252 = 252**
