Factors are the numbers that divide another number equally, without leaving any remainder. When you multiply two numbers to find another number, the two which are multiplied are factors. You can think of factors as the building blocks that will help you make numbers.

What are the factors of 768?

Factors are the numbers that help us divide things equally without any leftovers. 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 256, 384, and 768 are the factors of 768. The number has both positive and negative integers that divide 768 without leaving any remainder. 
 

How to find the factors of 768?

Factors help us divide numbers equally, making calculations faster and easier. Given below are the methods used to find factors: 
 

Finding Factors Using Multiplication

In this method, we take two numbers and find the product of those two numbers to get the required number.


Example: 1×768=768


2 × 384=768


3 × 256=768


4 × 192=768


6x128=768


Thus, the pairs are:


(1, 768), (2, 384), (3, 256), (4, 192), (6, 128), and so on.

Finding Factors by Division Method

We divide 768 by numbers starting from 1 and see which number gives the remainder of 0.


768 2=384


768 3=256


768 4=192


Similarly, we continue to list other factors.


Now, we know that the factors of 768 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 256, 384, and 768. 
 

Prime Factorization

The breaking down of numbers as prime factors is called prime factorization. The factors of 768 are:


768=28 x 3
 

Factor tree

A factor tree shows how a number can be parted down into prime factors.768 is broken down into two factors until we reach prime numbers 2 and 3.
 

Factor Pairs

Positive and negative pairs:


The factors of a number will have both the positive and negative numbers:


Positive factors: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 256, 384, 768


Negative factors: −1,−2,−3,−4,−6,−8,−12,−16,−24,−32,−48,−64,−96,−128,−256,−384,−768
