# What are all the factors, the prime factorization, and factor pairs of 3928?

To find the factors of 3928, divide 3928 by each number starting with 1 and working up to 3928

## What is a factor in math ?

Factors are the numbers you multiply together to get another number. For example, the factors of 15 are 3 and 5 because 3 × 5 = 15.

The factors of a number can be positive or negative, but they cannot be zero.

The factors of a number can be used to find out if the number is prime or not.

A prime number is a number that has only two factors: itself and 1. For example, the number 7 is prime because its only factors are 7 and 1.

## List all of the factors of 3928 ?

To calculate the factors of 3928 , you can use the division method.

1. Begin by dividing 3928 by the smallest possible number, which is 2.

2. If the division is even, then 2 is a factor of 3928.

3. Continue dividing 3928 by larger numbers until you find an odd number that does not divide evenly into 3928 .

4. The numbers that divide evenly into 3928 are the factors of 3928 .

Now let us find how to calculate all the factors of Three thousand nine hundred twenty-eight :

3928 ÷ 1 = 3928
3928 ÷ 2 = 1964
3928 ÷ 4 = 982
3928 ÷ 8 = 491
3928 ÷ 491 = 8
3928 ÷ 982 = 4
3928 ÷ 1964 = 2
3928 ÷ 3928 = 1

As you can see, the factors of 3928 are 1 , 2 , 4 , 8 , 491 , 982 , 1964 and 3928 .

## How many factors of 3928 are there ?

The factors of 3928 are the numbers that can evenly divide 3928 . These numbers are 1 , 2 , 4 , 8 , 491 , 982 , 1964 and 3928.

Thus, there are a total of 8 factors of 3928

## What are the factor pairs of 3928 ?

Factor Pairs of 3928 are combinations of two factors that when multiplied together equal 3928. There are many ways to calculate the factor pairs of 3928 .

One easy way is to list out the factors of 3928 :
1 , 2 , 4 , 8 , 491 , 982 , 1964 , 3928

Then, pair up the factors:
(1,3928),(2,1964),(4,982) and (8,491) These are the factor pairs of 3928 .

## Prime Factorisation of 3928

There are a few different methods that can be used to calculate the prime factorization of a number. Two of the most common methods are listed below.

1) Use a factor tree :

1. Take the number you want to find the prime factorization of and write it at the top of the page

2. Find the smallest number that goes into the number you are finding the prime factorization of evenly and write it next to the number you are finding the prime factorization of

3. Draw a line under the number you just wrote and the number you are finding the prime factorization of

4. Repeat step 2 with the number you just wrote until that number can no longer be divided evenly

5. The numbers written on the lines will be the prime factors of the number you started with

For example, to calculate the prime factorization of 3928 using a factor tree, we would start by writing 3928 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 3928 would be 2 x 2 x 2 x 491.

2) Use a factorization method :

There are a few different factorization methods that can be used to calculate the prime factorization of a number.

One common method is to start by dividing the number by the smallest prime number that will divide evenly into it.

Then, continue dividing the number by successively larger prime numbers until the number has been fully factorised.

For example, to calculate the prime factorization of 3928 using this method, we keep dividing until it gives a non-zero remainder.

3928 ÷ 2 = 1964
1964 ÷ 2 = 982
982 ÷ 2 = 491
491 ÷ 491 = 1

So the prime factors of 3928 are 2 x 2 x 2 x 491.
