# What are all the factors, the prime factorization, and factor pairs of 1590?

To find the factors of 1590, divide 1590 by each number starting with 1 and working up to 1590

## 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 1590 ?

To calculate the factors of 1590 , you can use the division method.

1. Begin by dividing 1590 by the smallest possible number, which is 2.

2. If the division is even, then 2 is a factor of 1590.

3. Continue dividing 1590 by larger numbers until you find an odd number that does not divide evenly into 1590 .

4. The numbers that divide evenly into 1590 are the factors of 1590 .

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

1590 ÷ 1 = 1590
1590 ÷ 2 = 795
1590 ÷ 3 = 530
1590 ÷ 5 = 318
1590 ÷ 6 = 265
1590 ÷ 10 = 159
1590 ÷ 15 = 106
1590 ÷ 30 = 53
1590 ÷ 53 = 30
1590 ÷ 106 = 15
1590 ÷ 159 = 10
1590 ÷ 265 = 6
1590 ÷ 318 = 5
1590 ÷ 530 = 3
1590 ÷ 795 = 2
1590 ÷ 1590 = 1

As you can see, the factors of 1590 are 1 , 2 , 3 , 5 , 6 , 10 , 15 , 30 , 53 , 106 , 159 , 265 , 318 , 530 , 795 and 1590 .

## How many factors of 1590 are there ?

The factors of 1590 are the numbers that can evenly divide 1590 . These numbers are 1 , 2 , 3 , 5 , 6 , 10 , 15 , 30 , 53 , 106 , 159 , 265 , 318 , 530 , 795 and 1590.

Thus, there are a total of 16 factors of 1590

## What are the factor pairs of 1590 ?

Factor Pairs of 1590 are combinations of two factors that when multiplied together equal 1590. There are many ways to calculate the factor pairs of 1590 .

One easy way is to list out the factors of 1590 :
1 , 2 , 3 , 5 , 6 , 10 , 15 , 30 , 53 , 106 , 159 , 265 , 318 , 530 , 795 , 1590

Then, pair up the factors:
(1,1590),(2,795),(3,530),(5,318),(6,265),(10,159),(15,106) and (30,53) These are the factor pairs of 1590 .

## Prime Factorisation of 1590

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 1590 using a factor tree, we would start by writing 1590 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 1590 would be 2 x 3 x 5 x 53.

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 1590 using this method, we keep dividing until it gives a non-zero remainder.

1590 ÷ 2 = 795
795 ÷ 3 = 265
265 ÷ 5 = 53
53 ÷ 53 = 1

So the prime factors of 1590 are 2 x 3 x 5 x 53.
