431
4 - 3 = 1
          432
  432 factors neatly into 2’s and 3’s
  432 = 2222333
  432 = 2[sup]4[/sup] * 3[sup]3[/sup]
note that the above equations only require the digits 4 3 and 2
          433
  433 is the sum of 2 squares 12[sup]2[/sup] + 17[sup]2[/sup]
          434
  434 is the sum of 2 consecutive primes 211 + 223
          435
  435 is the 29th triangular number, being the sum of the integers 1 through 29.
          436
436 is the sum of 2 squares 20[sup]2[/sup] + 6[sup]2[/sup]
Okay, think I’ll take a rest and leave some numbers for other people. I don’t want to be selfish and keep all the numbers for myself LOL.
437 is the product of 2 consecutive primes 19 * 23 = 437
          438
  438 is the sum of 16 consecutive primes 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, and 59
          439
  43 + 9 =   52
  43 * 9 = 387
  TOTAL = 439
          439
  43 + 9 =   52
  43 * 9 = 387
  TOTAL = 439
          440
  This is the frequency standard for musical instruments.
  The note A above middle C has a frequency of 440 cycles per second.
Sorry for the double posting, The board is S - L - O - W tonight.
Maybe it took so long (10 minutes) for the previous posting, that the server posted it twice (because I sure didn’t).
          441
  441 is a perfect square = 21[sup]2[/sup]
And now, as foreshadowed by Mudshark:
The 1969 Oldsmobile 442
          443
  443 is the sum of 11 consecutive primes:
  19, 23, 29, 31, 37, 41, 43, 47, 53, 59 & 61
          444
  37 is the 12th prime number.
  37 and 12 are 2 factors of 444
  37 * 12 = 444
          445
  445 is the sum of 2 squares = 11[sup]2[/sup] + 18[sup]2[/sup]
