What is the best way I can compress a number that has 540,000 digits?
<p>I have a number that has about 540,000 digits and I want to compress this number to a reasonable length since 540,000 is kinda absurd. What would be the best compression algorithm for this and how small can I compress it to?</p>

<p>A little background: Basically I have a picture that is 200 pixels wide and 300 pixels long. I'm taking out the red green blue values of each pixel. So each pixel is represented with 9 digits (because each red green value is represented with a number between 0 - 255). The picture has 60000 pixels in total. So representing this picture as a number would equate to a number equal to 9 x 60000 = 540,000.</p>
