2017年10月9日 · I was recently coding a prime factorization function and wanted to test that it could factor large numbers reasonably well. Arbitrarily, I slid my finger across the number pad, and got 23456789 as a test input. Surprisingly, it was prime! Was this just a strange coincidence, or is there any deeper number theoretic structure that leads to this ...

Here's a challenge : find the shortest way to write the number 1234567890 1234567890 . There is several ways to write the number 1234567890 1234567890 : 1.23456789 ×109 1.23456789 × 10 9 2 ×32 × 5 × 3607 × 3803 2 × 3 2 × 5 × 3607 × 3803 617283945 × 2 617283945 × 2 But all these notations are longer. Can you find a shorter notation than 1234567890 1234567890 ? EDIT : …

2015年5月29日 · Given the sequence 123456789: You can insert three operations ($+$,$-$,$\\times$,$/$) into this sequence to make the equation = 100. My question is: is there a way to solve this without brute forc...

2013年5月20日 · Many years ago, I noticed that 987654321 / 123456789 = 8.0000000729…. I sent it in to Martin Gardner at Scientific American and he published it in his column!!! My life has gone downhill since then:) My questions are: Why is this so? What happens beyond the " 729 729 "? What happens in bases other than 10 10 ?

While messing around, I noticed that across some prime numbers contain only sequentially increasing digits, e.g. 23, 67, 89, 23456789 23, 67, 89, 23456789. If we adopt a convention of returning to 1 1 after a 9 9, we can find some other primes, e.g. 67891, 4567891, 56789123, 1234567891, 4567891234567 67891, 4567891, 56789123, 1234567891 ...
