Factors are numbers that divide evenly into another number. Understanding factors is crucial in math since it helps us break down and solve more complex problems.
Today, we are going to talk about the factors of the number 8.
Whether you’re just starting out or looking to brush up on your skills, learning about factors can be both fun and useful.
What Are Factors?
Factors of a number are the integers that can be multiplied together to equal that original number. They divide the number completely, leaving no remainder.
For instance, the factors of 8 are the numbers that you can multiply together to get 8.
Knowing how to find the factors of a number can help you with many math problems, such as simplifying fractions or finding the greatest common divisor.

How To Calculate The Factors of 8
Calculating factors involves finding all the numbers that can divide into 8 without leaving a remainder. There are different methods to do this, including the multiplication method and the division method.
Both are easy to understand and can be applied to find the factors of other numbers as well.
Calculating Factors of 8 Using The Multiplication Method
In the multiplication method, you need to find pairs of numbers that, when multiplied together, give you 8. Here’s how you do it:
- Start with 1 because 1 multiplied by any number gives that number:
- 1 x 8 = 8
- Next, try 2 because 2 is the smallest prime number after 1:
- 2 x 4 = 8
- Continue checking if higher numbers up to half of 8 can be multiplied to get 8:
- Since we used 4 in the previous step, and 4 is half of 8, we are now done.
So, the pairs we have are: 1 x 8 and 2 x 4
Calculating Factors of 8 Using The Division Method
The division method involves dividing 8 by different whole numbers and seeing if the result is an integer (a whole number).
- Divide 8 by 1:
- 8 ÷ 1 = 8 (which is an integer)
- Divide 8 by 2:
- 8 ÷ 2 = 4 (which is an integer)
- Divide 8 by 3:
- 8 ÷ 3 = approximately 2.67 (which is not an integer)
- Divide 8 by 4:
- 8 ÷ 4 = 2 (which is an integer)
- Divide 8 by 5, 6, and 7:
- All result in non-integers
Thus, the numbers that divide 8 evenly are 1, 2, 4, and 8.
What Is Prime Factorization?
Prime factorization involves breaking down a composite number into a product of prime numbers. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.
For 8, we need to figure out which prime numbers, when multiplied together, result in 8.
