it was funny when the brown paper suddenly showed up at the blackboard. No Numberphile video without brown paper, even if there is a blackboard ready to be used. EDIT: haha, there is a second one at 1:33

If you think that's freaky, try 3 x 7 x (3 + 7 + 3) x 37 x 37 And see what you get.

+Paulxo Try 37 x 73, reverse the number you get and then add it to the original answer.

Here's a cool one for ya: "Three sevens equals three times seven times three seven." 777 = 3 x 7 x 37

No doubt, though not those where the base number - 1 is a prime, I would have thought, but please check. (By the way, I made an error in my last comment. Should have said any 5-repdigit in base 16 divided by its digit sum gives 369D)

Yes, and you'll find similar examples in other bases.

I see 37 all the time.

37 is my favorite number:)

Works because 3 x 37 = 111. Another interesting product to exploit is 73 x 137 = 10001
