What are all the factors, the prime factorization, and factor pairs of 1445?

To find the factors of 1445, divide 1445 by each number starting with 1 and working up to 1445

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 1445 ?

To calculate the factors of 1445 , you can use the division method.

   1. Begin by dividing 1445 by the smallest possible number, which is 2.

   2. If the division is even, then 2 is a factor of 1445.

   3. Continue dividing 1445 by larger numbers until you find an odd number that does not divide evenly into 1445 .

   4. The numbers that divide evenly into 1445 are the factors of 1445 .

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

    1445 ÷ 1 = 1445
    1445 ÷ 5 = 289
    1445 ÷ 17 = 85
    1445 ÷ 85 = 17
    1445 ÷ 289 = 5
    1445 ÷ 1445 = 1

As you can see, the factors of 1445 are 1 , 5 , 17 , 85 , 289 and 1445 .

Prime Factorisation of 1445

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 1445 using a factor tree, we would start by writing 1445 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 1445 would be 5 x 17 x 17.

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 1445 using this method, we keep dividing until it gives a non-zero remainder.

    1445 ÷ 5 = 289
    289 ÷ 17 = 17
    17 ÷ 17 = 1

So the prime factors of 1445 are 5 x 17 x 17.
