What are all the factors, the prime factorization, and factor pairs of 440?

To find the factors of 440, divide 440 by each number starting with 1 and working up to 440

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 440 ?

To calculate the factors of 440 , you can use the division method.

   1. Begin by dividing 440 by the smallest possible number, which is 2.

   2. If the division is even, then 2 is a factor of 440.

   3. Continue dividing 440 by larger numbers until you find an odd number that does not divide evenly into 440 .

   4. The numbers that divide evenly into 440 are the factors of 440 .

Now let us find how to calculate all the factors of Four hundred forty :

    440 ÷ 1 = 440
    440 ÷ 2 = 220
    440 ÷ 4 = 110
    440 ÷ 5 = 88
    440 ÷ 8 = 55
    440 ÷ 10 = 44
    440 ÷ 11 = 40
    440 ÷ 20 = 22
    440 ÷ 22 = 20
    440 ÷ 40 = 11
    440 ÷ 44 = 10
    440 ÷ 55 = 8
    440 ÷ 88 = 5
    440 ÷ 110 = 4
    440 ÷ 220 = 2
    440 ÷ 440 = 1

As you can see, the factors of 440 are 1 , 2 , 4 , 5 , 8 , 10 , 11 , 20 , 22 , 40 , 44 , 55 , 88 , 110 , 220 and 440 .

Prime Factorisation of 440

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 440 using a factor tree, we would start by writing 440 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 440 would be 2 x 2 x 2 x 5 x 11.

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

    440 ÷ 2 = 220
    220 ÷ 2 = 110
    110 ÷ 2 = 55
    55 ÷ 5 = 11
    11 ÷ 11 = 1

So the prime factors of 440 are 2 x 2 x 2 x 5 x 11.
