Prime root

Today, I will invent something (ridiculous).

I will invent the prime root (unofficially).

You have to take a number's prime factors and add them.

And Then take that number's prime factors and add them.

Continue doing that until you get a prime number. That is (unofficially) the prime root.

Say for example we have 15. The prime factors are 3 and 5. Add them and we get 8. The prime factors are 2 but there are 3 of them, So 2+2+2=6. The prime factors of it is 2 and 3. Add them and we get 5. STOP! We got a prime number. So the prime root of 15 is 5 (unofficially).

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

How you got this step :

The prime factors are 2 but there are 3 of them, So 2+2+2=6.

Because 2^3 =8 and we can just multiply 2 by 3 to get the sum of the factors (unofficially).

Remember! This is just nonsense
