# Readers ask: What is the prime factorization?

## How do you find the prime factorization?

Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Step 2: Write the number as a product of prime numbers.

## What is the prime factorization mean in math?

” Prime Factorization ” is finding which prime numbers multiply together to make the original number.

## What is prime factorization example?

A factor that is a prime number. In other words: any of the prime numbers that can be multiplied to give the original number. Example: The prime factors of 15 are 3 and 5 (because 3×5=15, and 3 and 5 are prime numbers).

## What is the prime factorization of 42?

The only way to write 42 as the product of primes (except to change the order of the factors ) is 2 × 3 × 7. We call 2 × 3 × 7 the prime factorization of 42. It turns out that every counting number (natural number) has a unique prime factorization, different from any other counting number.

## What is the prime factorization of 63?

So, the prime factorisation of 63 is 3 × 3 × 7 or 32 × 7, where 3 and 7 are the prime numbers.

## What is the prime factorization of 77?

The factors of 77 by prime factorization are 1, 7, 11, and 77. Here, 1, 7, and 11 are prime factors of 77.

## What is the difference between prime factorization and factorization?

Factors are numbers that can be multiplied together to make another number. Prime numbers are numbers that have exactly two factors, 1 and itself (i.e. 2, 3, 5, 7, 11,.). So, prime factorization is writing the prime numbers that will multiply together to make a new number as a multiplication problem.
