Question

A number is written with the following factorization 2x2x2x4x5. Is this factorization is prime factorization? Explain why or why not. If it is not correct, give the prime factorization of the number.

Answer 1

The number 2*2*2*4*5 is not in its prime factorization because not all the factors are prime numbers. A prime number is a number that has no other factors except for 1 and itself.
4 is not a prime number, since it can be divided by 2. The number can be broken down into its prime factors by dividing by 2, and it becomes 2*2.

Therefore, the factorization of the number 2*2*2*4*5 can be broken down to 2*2*2*2*2*5.
