# Factors of 75: Prime Factorization, Methods, Tree, and Examples

**Factors of 75**refer to the numbers by which 75 can completely be divided or they are those numbers whose product is 75 when two numbers are multiplied together. Hence, the number is referred to as a factor if it divides 75 with a remainder of 0. List all the numbers that are less than or equal to the number you are looking for to check the factors of that number. For instance, the numbers for 75 will range from 1 to 25. The solution can then be obtained by dividing each of them. Two is the factor of all numbers, which is a fascinating fact about factors. However, there are two methods for determining a number’s factors:

**division and multiplication**. Integer factors can be discovered in a variety of ways, though. There is a strategy to discover factors of an even simpler number. You simply keep dividing the number until the remainder equals zero, at which point you take the quotient and divisor as factors of the particular number. Let’s look at one of these situations as an example. If you divide 75 by 5, the answer will be 15. Therefore, both the divisor and the answer are regarded as factors. Altogether, they are known as factor pairs i.e. (5,15). For better understanding, this article will guide you about all the details related to

**factors of 75**in the best way possible. It consists of effortless solutions, amazing examples, and fun facts about the number 75.

## What Are the Factors of 75?

**The factors of 75 are 1, 3, 5, 15, 25, and 75. As 75 is a composite number it has more than 2 factors.**The factor pairs are (1,75), (3,25) and (5,15). You can achieve it by pairing the integers so that the result is 75. Whenever 75 is reduced (divided) by these figures, the answer is always 0.

## How To Calculate Factors of 75?

You can use two methods to determine the**factors of 75**: division and multiplication method. First, let’s look at how to find the factors through division. Find all the figures that are less than or equal to 75. Then divide 75 by each of the numbers. The

**factors of 75**are the divisors that cause the remainder to equal 0. To better understand this idea, look at the following example given below. Using the smallest factor of 75 (except 1) which is 3, we divide 75 by 3 which gives us 25. Thus 3 and 25 are the

**factors of 75**. \[ \frac {75}{3} = 25 \] This shows that both divisor and quotient (3 and 25) are factors of 75 as the quotient is a whole number and has no remainder. All the possible

**divisions of 75**are listed below: \[ \frac{75}{1} = 75 \] \[ \frac{75}{3} = 25 \] \[ \frac{75}{5} = 15 \] \[ \frac{75}{15} = 5 \] \[ \frac{75}{25} = 3 \] Therefore, all the factors are listed below:

**Factors: 1, 3, 5, 15, 25, 75**Now let’s focus on how to determine the factors through multiplication. In all conceivable ways, represent 75 as the product of two numbers. The factors of 75 are all those integers that are involved in all of these products. For example:

**1 x 75 = 75 **

**3 x 25= 75**

**5 x 15= 75 **

**1, 3, 5, 15, 25**, and

**75**are the factors of 75.

## Factors of 75 by Prime Factorization

One technique to express a particular number as the product of its prime factors is through the method of**prime factorization**, which involves determining which prime factors can multiply with one another to yield the number as a product. In other words, it is the method of finding or expressing the given number as the product of

**prime numbers**. A prime number only has two factors, 1 and the number itself. Since 75 is a

**composite number**, it ought to contain prime factors. Let’s learn how to determine the prime factors. The very first method is to divide 75 by the smallest prime factor, for example, let’s take 2. 75/2 will yield a fractional number if we divide it, thus we may move on to the following prime number, which is 3. This is shown below: \[ \frac{75}{3} = 25 \] The result of dividing 25 by 3 is a fractional number, which is not a factor. Hence, we proceed to the next prime number that is: \[ \frac{25}{5} = 5 \] \[ \frac{5}{5} = 1 \] After the division process, we received the number 1. Thus, preventing us from moving on. Thereby, the

**prime factors**of 75 mathematically can be represented as:

**3 x $5^{2}$= 16 **

## Factor Tree of 75

Even the factors of a number can be represented in several different ways. One of the numerous ways to**graphically display**the prime factors of a particular number is to express factors through a Factor Tree. The number itself is the root of the

**factor tree**, and from there, the branches represent factors until you reach the prime number. Therefore, according to prime factorization 3 and 5 are the prime factors of 75. So, 5 should be the last number to be represented on the factor tree. You can see the Factor tree of 75 attached below: Listed below are some fascinating fun facts about the number 75:

- The fourth ordered
**Bell number**, 75, tracks the number of weak orderings among a group of four things. - A
**pentagonal pyramidal**number75 is created by adding the first five pentagonal numbers together. Also, the number 75 is nonagonal and natural. - 75 is a
**Keith number**. Because there isn’t an integer whose digits when added together equal 75, it is a self-number. - In the third dimension, there are 75
**uniform Polyhedra**which include 7 families of prisms and antiprisms. - 75 is
**Rhenium’s atomic number**and the maximum age for senators from Canada. Furthermore, it is the department number of the city of Paris.

## Factors of 75 in Pairs

When multiplied together, a pair of two integers is known as a**factor pair**which produces the number itself as the result e.g. If 1 multiplied by 75 is 75, then (1, 75) is a pair factor of 75. Similarly, other factor pairs of 75 are as follows:

**1 x 75 = 75 **

**3 x 25 = 75 **

**5 x 15 = 75 **

**(1, 75), (3, 25)**, and

**(5, 15)**. Hence, these are the positive

**factor pairs of 75**. To find out the negative factor pair, all you have to do is to reverse the signs. The negative factor pairs are as follows:

**-1 x -75 = -75 **

**-3 x -25 = -75 **

**-5 x -15 = -75 **

**(-1, -75), (-3, -25)**, and

**(-5, -15)**.
