Factors of 981
So you need to find the factors of 981 do you? In this quick guide we'll describe what the factors of 981 are, how you find them and list out the factor pairs of 981 for you to prove the calculation works. Let's dive in!
Factors of 981 Definition
When we talk about the factors of 981, what we really mean is all of the positive and negative integers (whole numbers) that can be evenly divided into 981. If you were to take 981 and divide it by one of its factors, the answer would be another factor of 981.
Let's look at how to find all of the factors of 981 and list them out.
How to Find the Factors of 981
We just said that a factor is a number that can be divided equally into 981. So the way you find and list all of the factors of 981 is to go through every number up to and including 981 and check which numbers result in an even quotient (which means no decimal place).
Doing this by hand for large numbers can be time consuming, but it's relatively easy for a computer program to do it. Our calculator has worked this out for you. Here are all of the factors of 981:
- 981 ÷ 1 = 981
- 981 ÷ 3 = 327
- 981 ÷ 9 = 109
- 981 ÷ 109 = 9
- 981 ÷ 327 = 3
- 981 ÷ 981 = 1
All of these factors can be used to divide 981 by and get a whole number. The full list of positive factors for 981 are:
1, 3, 9, 109, 327, and 981
Negative Factors of 981
Technically, in math you can also have negative factors of 981. If you are looking to calculate the factors of a number for homework or a test, most often the teacher or exam will be looking for specifically positive numbers.
However, we can just flip the positive numbers into negatives and those negative numbers would also be factors of 981:
-1, -3, -9, -109, -327, and -981
How Many Factors of 981 Are There?
As we can see from the calculations above there are a total of 6 positive factors for 981 and 6 negative factors for 981 for a total of 12 factors for the number 981.
There are 6 positive factors of 981 and 6 negative factors of 981. Wht are there negative numbers that can be a factor of 981?
Factor Pairs of 981
A factor pair is a combination of two factors which can be multiplied together to equal 981. For 981, all of the possible factor pairs are listed below:
- 1 x 981 = 981
- 3 x 327 = 981
- 9 x 109 = 981
Just like before, we can also list out all of the negative factor pairs for 981:
- -1 x -981 = 981
- -3 x -327 = 981
- -9 x -109 = 981
So there you have it. A complete guide to the factors of 981. You should now have the knowledge and skills to go out and calculate your own factors and factor pairs for any number you like.
