Warning to iPhone owners: If you click on the composite number, the phone will offer to make a phone call.
Adding a leading zero didn’t help. That’s also some kind of phone number.
Life is weird.

1. "odd" used in this sense means that it is not an even number. n/t

2. All prime numbers are odd numbers, except for the number "2".

[John1956PA]

3. Yes. Of course, as we all know 1135809 is not a prime number.

In my reply above, I pointed out that the use of the word "odd" in the OP referred to the fact that it is not an even number. At first blush reading the OP, I thought that it was trying to convey the notion that there is something peculiar about the number. My intention was to clarify that "odd" was not being used in that sense.

4. I understand, but probably 75-80% of people don't know that...

Even numbers can't be prime numbers, maybe lesser percentages of DU members.

It's a sad fact of our education system today & the right is trying their hardest to make it worse.

Fight for education!

16. I knew that!

Math was always my worst subject in school, and I've always felt like a failure at it, but I knew that. Go figure.

I don't feel so dumb after all!

5. I copied and pasted that from the first website verbatim.

Perhaps their algo kicked it out.

[John1956PA]

7. Yes, I always knew that the choice of words was theirs, not yours.

After posting my comment about "OP" it crossed my mind that it seemed that I was blaming you for the word choice. Regardless, I am glad that you posted the piece. I learned about the site which factors large numbers and displays their roots.

8. I figured that. No prob.

I was having some fun with that number ( I presume you know its relevance, Georgia-wise)

The post was part of one that got taken down because I also mentioned that it's the part number of a pack of mop heads, and presumably (?) I was selling the mop heads. .

Hey, the math fact is so cool that it stands alone.

I found "NUMBER The Language of Science" early on. Never amounted to much in math. Just enough.

Life in the weird lane. It's fun. Not everyone understands. Their problem, not mine.

10. Right after the booking, I jumped on the mathematics of the number.

I posted a reply which reads, "Not a prime number." I was aiming for the type of disconnected side comments 45 makes when he is rambling. The mop "part number" removal which your original post experienced is amusing. Upthread, there was a comment that all the digits are primes or powers of primes. I do not think that is significant, since the number 6 is the only digit which exists and does not fit that description. It is fun to kick around number trivia based upon lessons which we all learned so long ago in math class.

[John1956PA]

13. Wow! Even the decimals have significance.

Your analysis is going to run in my memory like a repeating decimal. Thanks for posting!

[Torchlight]

15. Sounds serious.

Good luck.

[John1956PA]

17. Hi, Torchlight. I am surprised the post (and maybe the poster) which I replied to got removed.

The poster wrote that 1135809 divided by 2024 is 561.170454545. The purpose of my comment was to thank him for pointing this out and to make an attempted humorous reference about the fact that the decimal contains two repeating digits (which, of course, run out to infinity). Oh well, in any case, there has probably been enough discussion about the number 1135809.

[John1956PA]

19. Hi, Torchlight. I have been meaning to reply to you, but my post keeps winding up in the wrong spot.

6. An interesting number. All of the digits except 9 are Fibonacci numbers and are...

primes or powers of primes.

The sum of the digits is the 4th power of 3.

[Jim__]

11. The sum of the digits is the 3rd power of 3.

As noted in the cited article, 1135809 is a harshad number, and, of course, 27 divides 1135809, as can be seen from the list of its prime components: 3 x 3 x 3 x 23 x 31 x 59 = (3 x 3 x 3) x 23 x 31 x 59.
