# What are all the factors, the prime factorization, and factor pairs of 1040?

To find the factors of 1040, divide 1040 by each number starting with 1 and working up to 1040

## 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 1040 ?

To calculate the factors of 1040 , you can use the division method.

1. Begin by dividing 1040 by the smallest possible number, which is 2.

2. If the division is even, then 2 is a factor of 1040.

3. Continue dividing 1040 by larger numbers until you find an odd number that does not divide evenly into 1040 .

4. The numbers that divide evenly into 1040 are the factors of 1040 .

Now let us find how to calculate all the factors of One thousand forty :

1040 ÷ 1 = 1040
1040 ÷ 2 = 520
1040 ÷ 4 = 260
1040 ÷ 5 = 208
1040 ÷ 8 = 130
1040 ÷ 10 = 104
1040 ÷ 13 = 80
1040 ÷ 16 = 65
1040 ÷ 20 = 52
1040 ÷ 26 = 40
1040 ÷ 40 = 26
1040 ÷ 52 = 20
1040 ÷ 65 = 16
1040 ÷ 80 = 13
1040 ÷ 104 = 10
1040 ÷ 130 = 8
1040 ÷ 208 = 5
1040 ÷ 260 = 4
1040 ÷ 520 = 2
1040 ÷ 1040 = 1

As you can see, the factors of 1040 are 1 , 2 , 4 , 5 , 8 , 10 , 13 , 16 , 20 , 26 , 40 , 52 , 65 , 80 , 104 , 130 , 208 , 260 , 520 and 1040 .

## How many factors of 1040 are there ?

The factors of 1040 are the numbers that can evenly divide 1040 . These numbers are 1 , 2 , 4 , 5 , 8 , 10 , 13 , 16 , 20 , 26 , 40 , 52 , 65 , 80 , 104 , 130 , 208 , 260 , 520 and 1040.

Thus, there are a total of 20 factors of 1040

## What are the factor pairs of 1040 ?

Factor Pairs of 1040 are combinations of two factors that when multiplied together equal 1040. There are many ways to calculate the factor pairs of 1040 .

One easy way is to list out the factors of 1040 :
1 , 2 , 4 , 5 , 8 , 10 , 13 , 16 , 20 , 26 , 40 , 52 , 65 , 80 , 104 , 130 , 208 , 260 , 520 , 1040

Then, pair up the factors:
(1,1040),(2,520),(4,260),(5,208),(8,130),(10,104),(13,80),(16,65),(20,52) and (26,40) These are the factor pairs of 1040 .

## Prime Factorisation of 1040

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 1040 using a factor tree, we would start by writing 1040 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 1040 would be 2 x 2 x 2 x 2 x 5 x 13.

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 1040 using this method, we keep dividing until it gives a non-zero remainder.

1040 ÷ 2 = 520
520 ÷ 2 = 260
260 ÷ 2 = 130
130 ÷ 2 = 65
65 ÷ 5 = 13
13 ÷ 13 = 1

So the prime factors of 1040 are 2 x 2 x 2 x 2 x 5 x 13.
