## Prime Factorisation of 81000

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 81000 using a factor tree, we would start by writing 81000 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 81000 would be 2 x 2 x 2 x 3 x 3 x 3 x 3 x 5 x 5 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 81000 using this method, we keep dividing until it gives a non-zero remainder.

81000 ÷ 2 = 40500
40500 ÷ 2 = 20250
20250 ÷ 2 = 10125
10125 ÷ 3 = 3375
3375 ÷ 3 = 1125
1125 ÷ 3 = 375
375 ÷ 3 = 125
125 ÷ 5 = 25
25 ÷ 5 = 5
5 ÷ 5 = 1

So the prime factors of 81000 are 2 x 2 x 2 x 3 x 3 x 3 x 3 x 5 x 5 x 5.
