# Factors of 150: Prime Factorization, Methods, Tree, And Examples

The**Factors of 150**are the numbers upon which the number 150 is completely divisible. Being completely divisible means that these numbers yield zero as the remainder when they act as the

**divisors**for the number 150. The Factors of 150 can also be categorized as those numbers which produce 150 as the product when the two numbers undergo multiplication with one another. In this scenario, the two factors together form a

**factor pair.**The number 150 is an

**even composite number**which indicates that this number will have more than two factors, apart from the number 1 and the number itself, in this case, 150. Therefore, the number 150 has a long list of factors, including the number 2 since it’s an even number. The factors of 150 can be determined through various mathematical processes such as the

**division method**and the

**prime factorization method**. These factors can also be pictorially represented via the

**factor tree.**In this article, we will dive into the details of all these factors and will go through the multiple methods which are used to determine these factors. Moreover, we will also cover some solved examples to better understand the concept of factors of 150.Â

## What Are the Factors of 150?

**The factors of 150 are the following: 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150. All these numbers give off zero as the remainder when they act as the divisors for the number 150.**As the number 150 is an even composite number so it has 12 factors in total. These 12 factors can form 6 factor pairs.Â

## How To Calculate the Factors of 150?

You can calculate the factors of 150 through various methods but one of the most reliable methods to do so is the**division method**. The division method, as the name itself suggests, is based on the operation of division. Prior to moving towards the application of the decision method on the number 150, it is first necessary to determine the

**range**in which these factors lie. This is because the number 150 is a big number and an infinite number of possibilities exist for factors. So to narrow down those possibilities, it is necessary to determine the range. The method for determining the range of the factors is to look for the half of that number. In this case, the number is 150 and it’s half is 75.Â So this indicates that the range of factors of 150 lies between

**1 and 75**. Therefore, the division method will be applied to the numbers existing between 1 and 75. The condition for a number to be verified as a factor is that when it undergoes the division method, the number must leave zero as the remainder and a whole number quotient. This quotient rendered through the division also acts as the factor for the original number. As for the factors of 150, we know that the number 1 and the number 150 already qualify as the factors. We also know that the number 150 is an even number so this indicates that the number 2 will also act as its factor. The division is shown below: \[ \frac{150}{2} = 75 \] The division of this quotient 75 with the number 150 is shown below: \[ \frac{150}{75} = 2 \] So the number 75 also qualifies to be a factor of 150. Additional factors of 150 are given below: \[ \frac{150}{1} = 150 \] \[ \frac{150}{3} = 50 \] \[ \frac{150}{5} = 30 \] \[ \frac{150}{6} = 25 \] \[ \frac{150}{10} = 15 \] \[ \frac{150}{15} = 10 \] \[ \frac{150}{25} = 6 \] \[ \frac{150}{30} = 5 \] \[ \frac{150}{50} = 3 \] \[ \frac{150}{150} = 1\] Hence, the total factors of 150 are given below:

**Factors of 150: 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150Â**The factors for any number can be both positive and negative. The only difference between the two factors is the sign. The positive factors have a positive (+) sign whereas the negative factors have a negative (-) sign. The list of negative factors of the number 150 is given below:

**Negative Factors of 150: -1, -2, -3, -5, -6, -10, -15, -25, -30, -50, -75, and -150**

## Factors of 150 by Prime Factorization

The**prime factorization**method is the method that is used to evaluate the prime factors for a given number. This method is based on the operation of division. In prime factorization, the entire division is carried out by

**prime numbers**only. Like every other division, whole number quotients are also produced in prime factorization as a result of the division. These whole number quotients are passed onto the next step where they become the dividend for a potential

**prime factor.**This process of division with prime numbers is continued till 1 is achieved at the end. The prime factorization of the number 150 is shown below:

**150 $\div$ 5 = 30**

**30 $\div$ 5 = 6**

**6 $\div$ 2 = 3**

**3 $\div$ 3 = 1**

**Prime Factorization of 150 = 2 x 3 x 5 x 5**

**Prime Factorization of 150 = 2 x 3 x $5^{2}$**

**Prime Factors of 150 = 2, 3, and 5**

## Factor Tree of 150

The**factor tree**is the technique for pictorially representing the prime factors. It has a tree-like structure with multiple branches holding various numbers. The factor tree only holds prime numbers in its last branches.Â The factor tree for the number 150 is shown in figure 3 below: As the figure depicts, the number 150 acts as the root number which splits into prime factors and a whole number quotient. The respective quotient produced then acts as the root number. This continues until only prime numbers are present at the end.Â

## Factors of 150 in Pairs

The factors of 150 also have the ability to exist in the form of pairs which are known as the**factor pairs.**A factor pair consists of two numbers that undergo the process of multiplication. As a result of this multiplication, the original number must be produced as the result. The number 150 has 12 factors in total so these 12 factors can exist in

**6 factor pairs**. These factor pairs are given below:

**1 x 150 = 150**

**2 x 75 = 150**

**3 x 50 = 150**

**5 x 30 = 150**

**6 x 25 = 150**

**10 x 15 = 150**

**Factor Pairs of 150 = (1, 150), (2, 75), (3, 50), (5, 30), (6, 25), and (10, 15)**The factor pairs of 150 can also be

**negative**factor pairs. The only specification required for negative factor pairs is that both the numbers within the pair must have a negative sign. This is because the multiplication of these negative numbers results in a positive product. The negative factor pairs are given below:

**-1 x -150 = 150**

**-2 x -75 = 150**

**-3 x -50 = 150**

**-5 x -30 = 150**

**-6 x -25 = 150**

**-10 x -15 = 150**

**Negative Factor Pairs of 150 = (-1, -150), (-2, -75), (-3, -50), (-5, -30), (-6, -25), and (-10, -15)**
