Adding a leading zero didnt help. Thats also some kind of phone number.
Life is weird.

(3,368 posts)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.

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

I don't feel so dumb after all!

(3,368 posts)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.

(13,796 posts)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.

(3,368 posts)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.

(3,368 posts)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.

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

(14,456 posts)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.
