Check the binary conversion
Read 10000001001 from right to left using place values 1, 2, 4, 8 and successive powers of two. Keep the values whose bit is 1:
1024 + 8 + 1 = 1033
Check the hexadecimal conversion
4 × 16^2 + 0 × 16^1 + 9 × 16^0 = 1033
Hexadecimal uses A through F for digit values 10 through 15. These notations represent the same quantity; changing the base does not change the integer.

For example, 1033 = 7 × 147 + 4. A remainder of zero is what makes a divisor a factor.
Digit sum and digital root of 1033
1033 contains 4 decimal digits. Its digit sum is 1 + 0 + 3 + 3 = 7.
- 1033: 1 + 0 + 3 + 3 = 7
The digital root is 7. Reversing its digits gives 3301; it is not a decimal palindrome. Digit patterns depend on the notation being used.
Digital-root arithmetic always finishes at a single digit for a positive integer. Some numerology methods stop at 11, 22 or 33 instead; that is a separate interpretive convention.
Fractions and a worked comparison
As a fraction of 100, 1033/100 simplifies to 1033/100 by dividing both terms by their greatest common divisor, 1. Its decimal value is 10.33. Because the numerator exceeds the denominator, this value is greater than one.
The greatest common divisor of 1033 and 12 is 1. Their least common multiple is 12396. The identity GCD × LCM = 1033 × 12 = 12396 checks both results.

A reflective note on 1033
Meaning varies by tradition and personal experience. One sighting is not evidence of what will happen next.
The digits of 1033 add to 7. That arithmetic result is separate from the cultural symbolism of the pattern. If this number matters to you, write down what you noticed and choose one grounded action rather than treating the sighting as a prediction.
