Prime Factorisation of 646400

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 646400 using a factor tree, we would start by writing 646400 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 646400 would be 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 x 5 x 101.

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 646400 using this method, we keep dividing until it gives a non-zero remainder.

    646400 ÷ 2 = 323200
    323200 ÷ 2 = 161600
    161600 ÷ 2 = 80800
    80800 ÷ 2 = 40400
    40400 ÷ 2 = 20200
    20200 ÷ 2 = 10100
    10100 ÷ 2 = 5050
    5050 ÷ 2 = 2525
    2525 ÷ 5 = 505
    505 ÷ 5 = 101
    101 ÷ 101 = 1

So the prime factors of 646400 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 x 5 x 101.
