# Factors of 315

If you’re a math enthusiast or a student, you must have heard about the “Factors of 315” at least once. The factors of 315 are the numbers that can be evenly divided into 315 without leaving a remainder. In other words, these are the numbers that multiply to give 315.

## Contents

Finding the factors of 315 is relatively simple, but it’s crucial to know the correct process. Let’s take a closer look at how to find the factors of 315.

## What are the Factors of 315?

A factor is a number that can be divided evenly into another number. Factors of a number can be used to find other important mathematical properties of that number, such as finding the prime factorization or finding the greatest common factor of two numbers. In this article, we’ll be discussing the factors of 315 and how to find them.

## Factors Calculator

To find the factors of a number, you can use a factors calculator. These calculators are simple tools that allow you to input a number and find its factors in seconds. While it’s easy to use a calculator, it’s also important to understand how to find the factors of a number manually, as this will help you build your math skills.

## How to Find the Factors of 315?

Firstly, list down all the factors of 315, including negative and positive factors. To start, you can divide 315 by the first positive integer 1. You will get 315 as a quotient and 0 as a remainder. It means 1 is a factor of 315.

Next, divide 315 by the next positive integer, which is 2. You will get 157 as a quotient and 1 as a remainder. As 2 didn’t evenly divide 315, it isn’t a factor of 315.

Now, move on to the next number, which is 3. After dividing 315 by 3, you will get 105 as a quotient and 0 as a remainder. It means 3 is a factor of 315.

Keep repeating this process for all the positive integers until you reach the square root of 315. The factors of 315 are {1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315}.

## Factors of (-315)

When considering negative factors, keep in mind that negative factors are the factors that can divide a negative number. The negative factors of 315 are {-1, -3, -5, -7, -9, -15, -21, -35, -45, -63, -105, -315}.

## Factors of 315 in Pairs

1 x 315 = 315
3 x 105 = 315
5 x 63 = 315
7 x 45 = 315
9 x 35 = 315
15 x 21 = 315

Factor pairs are pairs of numbers that, when multiplied together, equal a given number. Therefore, the factor pairs of 315 are (1, 315), (3, 105), (5, 63), (7, 45), (9, 35), and (15, 21) are the six pairs of factors of 315.

-1 x -315 = 315
-3 x -105 = 315
-5 x -63 = 315
-7 x -45 = 315
-9 x -35 = 315
-15 x -21 = 315

So, (-1, -315), (-3, -105), (-5, -63), (-7, -45), (-9, -35), and (-15, -21) are negative pair factors of 315.

## All Factors of 315

The all factors of 315 are -1, -3, -5, -7, -9, -15, -21, -35, -45, -63, -105, -315, 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105 and 315. These are the numbers that can be evenly divided into 315.

## Prime Factors of 315

315 ÷ 3 = 105
105 ÷ 3 = 35
35 ÷ 5 = 7
7 ÷ 7 = 1

So, the prime factorization of 315 is 3 x 3 x 5 x 7.

## Factor Tree of 315

Another method to find the factors of 315 is to use a factor tree. Start with any two factors of 315, and keep breaking them down into their factors until you get all the prime factors. Here is a factor tree of 315:
