Quick Answer: What Does It Mean To Write The Prime Factorization Of A Number?

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

  1. Put a prime factor on the outside left, and the result or quotient (the number of times it divides evenly) underneath.
  2. 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.
