# What are all the factors, the prime factorization, and factor pairs of 12500?

To find the factors of 12500, divide 12500 by each number starting with 1 and working up to 12500

## 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 12500 ?

To calculate the factors of 12500 , you can use the division method.

1. Begin by dividing 12500 by the smallest possible number, which is 2.

2. If the division is even, then 2 is a factor of 12500.

3. Continue dividing 12500 by larger numbers until you find an odd number that does not divide evenly into 12500 .

4. The numbers that divide evenly into 12500 are the factors of 12500 .

Now let us find how to calculate all the factors of Twelve thousand five hundred :

12500 ÷ 1 = 12500
12500 ÷ 2 = 6250
12500 ÷ 4 = 3125
12500 ÷ 5 = 2500
12500 ÷ 10 = 1250
12500 ÷ 20 = 625
12500 ÷ 25 = 500
12500 ÷ 50 = 250
12500 ÷ 100 = 125
12500 ÷ 125 = 100
12500 ÷ 250 = 50
12500 ÷ 500 = 25
12500 ÷ 625 = 20
12500 ÷ 1250 = 10
12500 ÷ 2500 = 5
12500 ÷ 3125 = 4
12500 ÷ 6250 = 2
12500 ÷ 12500 = 1

As you can see, the factors of 12500 are 1 , 2 , 4 , 5 , 10 , 20 , 25 , 50 , 100 , 125 , 250 , 500 , 625 , 1250 , 2500 , 3125 , 6250 and 12500 .

## How many factors of 12500 are there ?

The factors of 12500 are the numbers that can evenly divide 12500 . These numbers are 1 , 2 , 4 , 5 , 10 , 20 , 25 , 50 , 100 , 125 , 250 , 500 , 625 , 1250 , 2500 , 3125 , 6250 and 12500.

Thus, there are a total of 18 factors of 12500

## What are the factor pairs of 12500 ?

Factor Pairs of 12500 are combinations of two factors that when multiplied together equal 12500. There are many ways to calculate the factor pairs of 12500 .

One easy way is to list out the factors of 12500 :
1 , 2 , 4 , 5 , 10 , 20 , 25 , 50 , 100 , 125 , 250 , 500 , 625 , 1250 , 2500 , 3125 , 6250 , 12500

Then, pair up the factors:
(1,12500),(2,6250),(4,3125),(5,2500),(10,1250),(20,625),(25,500),(50,250) and (100,125) These are the factor pairs of 12500 .

## Prime Factorisation of 12500

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 12500 using a factor tree, we would start by writing 12500 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 12500 would be 2 x 2 x 5 x 5 x 5 x 5 x 5.

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 12500 using this method, we keep dividing until it gives a non-zero remainder.

12500 ÷ 2 = 6250
6250 ÷ 2 = 3125
3125 ÷ 5 = 625
625 ÷ 5 = 125
125 ÷ 5 = 25
25 ÷ 5 = 5
5 ÷ 5 = 1

So the prime factors of 12500 are 2 x 2 x 5 x 5 x 5 x 5 x 5.
