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 438400 using a factor tree, we would start by writing 438400 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 438400 would be 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 x 5 x 137.

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 438400 using this method, we keep dividing until it gives a non-zero remainder.

    438400 ÷ 2 = 219200
    219200 ÷ 2 = 109600
    109600 ÷ 2 = 54800
    54800 ÷ 2 = 27400
    27400 ÷ 2 = 13700
    13700 ÷ 2 = 6850
    6850 ÷ 2 = 3425
    3425 ÷ 5 = 685
    685 ÷ 5 = 137
    137 ÷ 137 = 1

So the prime factors of 438400 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 x 5 x 137.
