Question

6. a) Rivka used the last four digits of her

telephone number, 1048, followed by
its prime factorization to create her
e-mail password. Determine her
password.

Answer 1

Answer: Her e-mail password is
`1048222131`

Explanation:

You know that a part of Rivka's e-mail password is formed by the last four digits of her telephone number.

The exercise gives you the last four digits of Rivka's telephone number:

`1048`

Now, in order to find the other numbers, you need to descompose
`1048` into its prime factors. Then:

`1048=2*2*2*131`

Therefore, based on this, you can determine that her e-mail password is:

`e-mail\ password=1048222131`
