463!
It depends on what sum you are estimating from.
If the question was 462+1, I would not estimate anything other than 463.
If the question was square root of 214,369, I would go for an estimate between 450 and 500.
The positive integer factors of 463 are: 1, 463
Only by 1 and 463 since 463 is a prime number.
463, 000
463-84 = 379
463-55 = 408
463 + 230 = 693
463% is 4.63
463 - 333 = 130
