Prime factorization is a **way of expressing a number as a product of its prime factors**. A prime number is a number that has exactly two factors, 1 and the number itself. The number 6 is expressed as 2 × 3 since 3 and 2 are prime numbers. Therefore, the prime factorization of 30 is 2 × 3 × 5.

## How do you write the prime factorization of a number?

How to Write Prime Factorization of Composite Numbers

- Put a prime factor on the outside left, and the result or quotient (the number of times it divides evenly) underneath.
- Divide the quotient (the number underneath) by another prime number, and keep doing this until the bottom number is a prime.

## What is an example of prime factorization?

Prime factorization is a process of factoring a number in terms of prime numbers i.e. the factors will be prime numbers. For example, prime factorising the number 30 we get, 30/2 = 15, 15/3 = 5, 5/5 = 1.

## What is the meaning of prime factorization?

Prime factorisation is a method to find the prime factors of a given number, say a composite number. A prime number is a number which has only two factors, i.e. 1 and the number itself. For example, 2 is a prime number which has two factors, 2 × 1.

## How do you write prime factorization of 50?

Factors of 50

- Factors of 50: 1, 2, 5, 10, 25, 50.
- Prime Factorization of 50: 2 × 5 × 5.

## How do you do prime factorization in math?

Division Method of Prime Factorization

- Step 1: Divide the number by the smallest prime number such that the smallest prime number should divide the number completely.
- Step 2: Again, divide the quotient of step 1 by the smallest prime number.
- Step 3: Repeat step 2, until the quotient becomes 1.

## What’s the prime factorization of 156?

The prime factorization of 156 is 2 × 2 × 3 × 13.

## What’s the prime factorization of 5?

5 is a prime number. Therefore, it can have only two factors, i.e., 1 and the number itself. The factors of 5 are 1 and 5.

## What’s the prime factorization of 9?

Prime factorization of 9 is 9 = 3 × 3.

## What is prime factor Math?

The factors of a number are numbers that evenly divide into it. A prime factor is a factor that is only divisible by 1 and itself. You can use a factor tree to help you find a number’s prime factorization.

## What is prime number and prime factor?

Prime numbers are numbers that have only 2 factors: 1 and themselves. For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. By contrast, numbers with more than 2 factors are call composite numbers.

## What’s the prime factorization of 81?

9 ÷ 3 = 3. Thus, we get the prime factorization of 81 = 3 × 3 × 3 × 3 which means that the only prime factor is 3.

## What is the prime factor 40?

What are the Prime Factors of 40? The prime factors of 40 are 2, 5.

## What is the prime factorization of 120?

So the prime factorization of 120 is 2^{3} × 3 × 5 In fact, 2, 3 and 5 are the prime factors of 120. Also, we know that 1 is a factor of every number. Thus, The factors of 120 by prime factorization are 1, 2, 3, 5, 15, 30, 60, and 120.
