  1.  @Patrik6920  But that's incorrect. He memorized the factors, but he performed the long multiplication on the board. He also computed 2^67 - 1 on the board. That's why people clapped. It took him years to find the factors, not to perform a single multiplication. It had already been proven that 2^67 - 1 was not prime, but no nontrivial proper factors were known until he found them.

  2. It would have taken forever lmao. Multiplying a 12 digit number by a 9 digit number takes 108 single-digit multiplications with carry and 81 single-digit additions plus carries. Then calculating 2^67 can be done as 2^3 * 2^2^6 = 8 * (((((2^2)^2)^2)^2)^2)^2 = 8 * (((256^2)^2)^2 = 8 * ((65536^2)^2 = 8 * 4294967296^2 = 8 * 18446744073709551616, requiring another 150ish multiplications. It probably took like twenty minutes just to do the calculations on the board.

  3. BTW, "Leonhard" is not "Leonard." It's pronounced like LEE-on-hart.
