Most common number of prime factors

I wrote some Python code to check what the most common number of prime factors is for all numbers between 11 and 1,000,0001,000,000 (it took a while!). For example, 1010 has two prime factors, 22 and 55, and 220220 has four: 22, 22, 55, and 1111. Here's what I got:

(Please forgive the odd x-axis scale. I forgot to set this before I ran the program.)

At first I checked numbers between 11 and 10,00010,000, and then 11 and 100,000100,000, and when I did this, it appeared that it was most common for a number to have 22 prime factors. But as I increased the upper bound, 33 prime factors became the most frequent.

I'm not sure if this would change once again with an even larger upper bound, because my laptop took about 20 minutes to do up to 1,000,0001,000,000. Does anyone have anything to add?

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.
