Factors of -75
Factors are the numbers that divide any given number evenly without a remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of -75, how they are used in real life, and tips to learn them quickly.
What are the Factors of -75?
The numbers that divide -75 evenly are known as factors of -75.
A factor of -75 is a number that divides the number without a remainder.
The factors of -75 are 1, 3, 5, 15, 25, and 75.
Negative factors of -75: -1, -3, -5, -15, -25, and -75.
Prime factors of -75: 3 and 5.
Prime factorization of -75: -1 × 3 × 5².
The sum of the positive factors of 75: 1 + 3 + 5 + 15 + 25 + 75 = 124
How to Find Factors of -75?
Factors can be found using different methods. Mentioned below are some commonly used methods:
- Finding factors using multiplication
- Finding factors using the division method
- Prime factors and prime factorization
Finding Factors Using Multiplication
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give -75. Identifying the numbers which are multiplied to get the number -75 is the multiplication method.
Step 1: Multiply -75 by 1, -75 × 1 = -75.
Step 2: Check for other numbers that give -75 after multiplying 3 × -25 = -75 5 × -15 = -75
Therefore, the positive factor pairs of -75 are: (1, -75), (3, -25), and (5, -15).
For every positive factor, there is a corresponding negative factor.
Finding Factors Using Division Method
Dividing the given numbers with whole numbers until the remainder becomes zero and listing out the numbers which result in whole numbers as factors. Factors can be calculated by following a simple division method
Step 1: Divide -75 by 1, -75 ÷ 1 = -75.
Step 2: Continue dividing -75 by the numbers until the remainder becomes 0.
-75 ÷ 1 = -75
-75 ÷ 3 = -25
-75 ÷ 5 = -15
Therefore, the factors of -75 are: 1, 3, 5, 15, 25, and 75.
Prime Factors and Prime Factorization
The factors can be found by dividing them with a prime number. We can find the prime factors using the following methods:
- Using prime factorization
- Using a factor tree
Using Prime Factorization: In this process, prime factors of -75 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.
-75 ÷ -1 = 75
75 ÷ 3 = 25
25 ÷ 5 = 5
5 ÷ 5 = 1
The prime factors of -75 are 3 and 5.
The prime factorization of -75 is: -1 × 3 × 5².
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, -75 is divided by -1 to get 75.
Step 2: Now divide 75 by 3 to get 25.
Step 3: Then divide 25 by 5 to get 5. Here, 5 is a prime number that cannot be divided anymore.
So, the prime factorization of -75 is: -1 × 3 × 5².
Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.
Positive factor pairs of -75: (1, -75), (3, -25), and (5, -15).
Negative factor pairs of -75: (-1, 75), (-3, 25), and (-5, 15).
