The Boeing 737 is the best selling commercial airline jet. It has been produced continuously since 1967. If you’ve ever flown Southwest Airlines, Ryanair, United Airlines, or American Airlines, chances are the 737 took you to your destination.
The next time you fly in a 737, use the following number facts to impress your seatmates. They will be so glad they sat next to you: 😉
7 – 3 + 7 = 11 so 737 is divisible by 11.
737 can be written as the sum of consecutive numbers three ways:
- 368 + 369 = 737; that’s 2 consecutive numbers.
- 62 + 63 + 64 + 65 + 66 + 67 + 68 + 69 + 70 + 71 + 72 = 737; that’s 11 consecutive numbers.
- 23 + 24 + 25 + 26 + 27 + 28 + 29 + 30 + 31 + 32 + 33 + 34 + 35 + 36 + 37 + 38 + 39 + 40 + 41 + 42 + 43 + 44 = 737; that’s 22 consecutive numbers.
737 is obviously a palindrome, but base 10 is not the only base that can make that claim:
- 737 base 10; note that 7(100) + 3(10) + 7(1) = 737.
- 515 BASE 12; note that 5(144) + 1(12) + 5(1) = 737.
- 191 BASE 23; note that 1(529) + 9(23) + 1(1) = 737.
