The factors of a number are all the numbers that can divide it exactly leaving no remainder. If a number has no remainder, it is a prime number. In this article we will be looking at the factors of the number 8.
We will start by finding all the numbers that can divide into it. We can do this by using trial division. The first number that divides into it is 2. Then we can find the other numbers that divide into it by starting with the smallest prime factor, which in this case is 1. Once we have all the factors of 8 we can then determine if it is a prime or composite number.
This is done by determining the number of factors it has. If it has only two factors (the number itself and 1) it is a prime number. If it has more than two factors, then it is a composite number.
The factors of the number 8 are 1, 2, 4, and 8. These are its positive factors. It also has negative factors which are represented by -1 and -2. The factors are listed below. We can use this list to find the factors of any other number. This is a helpful tool for when you are trying to solve an equation. It can save you a lot of time and effort by not having to manually calculate each individual number. This is especially helpful when you are solving a large equation that has many factors.
