## A Multiplication Based Logic Puzzle

### 41 and Life Is Like A Sudoku Puzzle

41 is a prime number. 41 = 1 x 41. Its only factors are 1 and 41. Prime factorization: none.

How do we know that 41 is a prime number? The square root of 41 is an irrational number approximately equal to 6.403. If 41 were not a prime number, then it would be divisible by at least one prime number less than or equal to 6.403. Since 41 is not divisible by 2, 3, or 5, it is a prime number.

41 is never a clue in the FIND THE FACTORS puzzles.

I read an essay titled Life Is Like a Sudoku Puzzle. Typically the only Sudoku puzzles I do are in the newspaper, and it has been weeks since I’ve started one. If I mess up on one, I don’t try to figure out what I did wrong. I simply put a big x on it and throw the paper in the recycling bin. I accept defeat, but I really don’t learn anything from my mistake. But if I would look at those puzzles a little differently, I could learn a lot about life from them, just as that essay suggests.
