## 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 2430 ?

To calculate the factors of 2430 , you can use the division method.

1. Begin by dividing 2430 by the smallest possible number, which is 2.

2430 ÷ 486 = 5
2430 ÷ 810 = 3
2430 ÷ 1215 = 2
2430 ÷ 2430 = 1

As you can see, the factors of 2430 are 1 , 2 , 3 , 5 , 6 , 9 , 10 , 15 , 18 , 27 , 30 , 45 , 54 , 81 , 90 , 135 , 162 , 243 , 270 , 405 , 486 , 810 , 1215 and 2430 .

## How many factors of 2430 are there ?

The factors of 2430 are the numbers that can evenly divide 2430 . These numbers are 1 , 2 , 3 , 5 , 6 , 9 , 10 , 15 , 18 , 27 , 30 , 45 , 54 , 81 , 90 , 135 , 162 , 243 , 270 , 405 , 486 , 810 , 1215 and 2430.

Thus, there are a total of 24 factors of 2430

## What are the factor pairs of 2430 ?

Factor Pairs of 2430 are combinations of two factors that when multiplied together equal 2430. There are many ways to calculate the factor pairs of 2430 .

One easy way is to list out the factors of 2430 :
1 , 2 , 3 , 5 , 6 , 9 , 10 , 15 , 18 , 27 , 30 , 45 , 54 , 81 , 90 , 135 , 162 , 243 , 270 , 405 , 486 , 810 , 1215 , 2430

Then, pair up the factors:
(1,2430),(2,1215),(3,810),(5,486),(6,405),(9,270),(10,243),(15,162),(18,135),(27,90),(30,81) and (45,54) These are the factor pairs of 2430 .

## Prime Factorisation of 2430

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 2430 using a factor tree, we would start by writing 2430 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 2430 would be 2 x 3 x 3 x 3 x 3 x 3 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 2430 using this method, we keep dividing until it gives a non-zero remainder.

2430 ÷ 2 = 1215
1215 ÷ 3 = 405
405 ÷ 3 = 135
135 ÷ 3 = 45
45 ÷ 3 = 15
15 ÷ 3 = 5
5 ÷ 5 = 1

So the prime factors of 2430 are 2 x 3 x 3 x 3 x 3 x 3 x 5.
