Factors of 729
So you need to find the factors of 729 do you? In this quick guide we'll describe what the factors of 729 are, how you find them and list out the factor pairs of 729 for you to prove the calculation works. Let's dive in!
Factors of 729 Definition
When we talk about the factors of 729, what we really mean is all of the positive and negative integers (whole numbers) that can be evenly divided into 729. If you were to take 729 and divide it by one of its factors, the answer would be another factor of 729.
Let's look at how to find all of the factors of 729 and list them out.
How to Find the Factors of 729
We just said that a factor is a number that can be divided equally into 729. So the way you find and list all of the factors of 729 is to go through every number up to and including 729 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 729:
- 729 ÷ 1 = 729
- 729 ÷ 3 = 243
- 729 ÷ 9 = 81
- 729 ÷ 27 = 27
- 729 ÷ 81 = 9
- 729 ÷ 243 = 3
- 729 ÷ 729 = 1
All of these factors can be used to divide 729 by and get a whole number. The full list of positive factors for 729 are:
1, 3, 9, 27, 81, 243, and 729
Negative Factors of 729
Technically, in math you can also have negative factors of 729. 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 729:
-1, -3, -9, -27, -81, -243, and -729
How Many Factors of 729 Are There?
As we can see from the calculations above there are a total of 7 positive factors for 729 and 7 negative factors for 729 for a total of 14 factors for the number 729.
There are 7 positive factors of 729 and 7 negative factors of 729. Wht are there negative numbers that can be a factor of 729?
Factor Pairs of 729
A factor pair is a combination of two factors which can be multiplied together to equal 729. For 729, all of the possible factor pairs are listed below:
- 1 x 729 = 729
- 3 x 243 = 729
- 9 x 81 = 729
- 27 x 27 = 729
Just like before, we can also list out all of the negative factor pairs for 729:
- -1 x -729 = 729
- -3 x -243 = 729
- -9 x -81 = 729
- -27 x -27 = 729
Notice in the negative factor pairs that because we are multiplying a minus with a minus, the result is a positive number.
So there you have it. A complete guide to the factors of 729. You should now have the knowledge and skills to go out and calculate your own factors and factor pairs for any number you like.
