Question 376688: Hi, I just happened to wonder what the prime factorization of 6857599914349403977654744967172758179904114264612947326127169976133296980951450542789808884504301075550786464802304019795402754670660318614966266413770127 was and I don't think your calculator (http://www.algebra.com/algebra/homework/divisibility/factor-any-number.solver) is giving me the right answer. It tells me:

could you maybe shed some light on the matter? I tried to get my Ti83 to work it out but it acted odd... Also, I don't think 5174413344875007990519123187618500139954995264909695897020209972309881454541 = 2^200 * 5^2 * 251003 * 513148501, because that would be 5174413344875008388754966029640933369099339830916797506938194267747857203200, and I'm also pretty sure 5174413344875007990519123187618500139954995264909695897020209972309881454541 and 1325290319363741258636842042448323483211759628292406959481461131759210884908747 are both prime. How come it's not giving me the right answer? Is there a good calculator (something better than Ti83) that would factor this kind of numbers for me? Thankx!

Try this page. In general, factoring large numbers into primes is a very hard problem (even for computers). So a number like yours might be too much to handle (for current technology anyway).
