## 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 prime factorisation of 16?

Therefore, the factors of 16 are 1, 2, 4, 8, and 16 and the prime factorization of 16 is 16 = 2 × 2 × 2 × 2.

### What is the prime factorisation of 57?

3 and 19
The prime factorization of 57 is the product of prime numbers which results in 57. From the prime factorization of 57, it is clear that 3 and 19 are the prime factors of 57. We know that 1 is the factor of every number. Thus, the factors of 57 by prime factorization are 1, 3, 19, and 57.

What is the GCF of 54 and 36?

18
Answer: GCF of 36 and 54 is 18.

## What is the prime factorisation of 128?
