What Are The Factors Of 6400 - Factor Pairs & Prime Factorization

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.

Prime Factorisation of 6400

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 6400 using a factor tree, we would start by writing 6400 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 6400 would be 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 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 6400 using this method, we keep dividing until it gives a non-zero remainder.

    6400 ÷ 2 = 3200
    3200 ÷ 2 = 1600
    1600 ÷ 2 = 800
    800 ÷ 2 = 400
    400 ÷ 2 = 200
    200 ÷ 2 = 100
    100 ÷ 2 = 50
    50 ÷ 2 = 25
    25 ÷ 5 = 5
    5 ÷ 5 = 1

So the prime factors of 6400 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 x 5.
