A safe amount of time has passed.
Today we know another prime factorization. Specifically, ifactor(1,357,928) is 2*2*2*11*13*1187. This doesn't get old. Matt

Finding the full factorization of any number below 30 digits is effectively trivial. I just fed a 30 digit semipirime into Dario's ECM site and it found the 2 factors, each 15 digits, in 0.2 seconds.
Why don't you toot your trumpet elsewhere. Like in a rideshare car. Last fiddled with by Uncwilly on 20210615 at 01:53

Hi again all,
Today's favorite mega number starts with 1.7 million. I like those numbers. And to avoid round numbers, I choose the number 1,712,121. We see that 1,712,121 = 3 * 17 * 59 * 569. I have a computer with special software, so I can do this factorization. Also, factordb.com has a Factorize! button, so the capability is also online. Additionally, Apertron has a nice online integer factorization calculator, so there are options. Not everyone has factorization software, or knows about those websites. I like to factor numbers.

In Mathematical Snapshots by Hugo Steinhaus there is a number called "mega." The notation is called "SteinhausMoser notation." The notation is, n in a triangle means n^n, n in a square is n in n triangles, and n in a circle means n in n squares. The number mega is 2 in a circle. OK, that's 2 in 2 squares. Now 2 in a square is 2 in 2 triangles. Two in a triangle is 2^2 or 4, and 4 in a triangle is 4^4 or 256. So mega is 256 in a square, or 256 in 256 triangles...
Steinhaus called the number 10 in a circle "megiston."

Hello interested parties,
Today’s meganumber is 1,222,222. Since I am only typing on my cell phone, I will not give you the joy of seeing its Prime factorization. That is all for now. Matt
