Answer 2

Answer:

Step-by-step explanation:

Concept:

Prime factorization:

Finding a number's prime factors in a way that the original number may be divided equally by them is known as prime factorization. Since a composite number might have more than two factors, this method can only be used with composite numbers rather than prime numbers.

Given:

The numbers are $20,128,72,81,2019,2729,6174,2020,1024,495$.

Find:

 To find the prime factorization of the given numbers.

Solution:

The prime factorization of $20$ is $2 * 2 * 5 or 22 * 5.$

The prime factorization of $128$ is $2 * 2 * 2 * 2 * 2 * 2 * 2.$

The prime factorization of $72$ is $2*2*2*3*3$.

The prime factorization of $81$ is $3*3*3*3$.

The prime factorization of $2019$ is  $3 * 673$.

The prime factorization of $2729$ is $2729 * 1$.

The prime factorization of $6174$ is $2*3*3*7*7*7$.

The prime factorization of $2020$ is $2 * 2 * 5 * 101$.

The prime factorization of $1024$ is $2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2.$

The prime factorization of $495$ is $3*3*5*11$.
