Cracking 1980s Encryption

Computer Science Level 4

Your uncle Omar has asked for your help. Back in the 1980s, he encrypted some personal documents using RSA encryption, but he lost his private key. He waited years for computers to become powerful enough to unlock his key, but then forgot about the documents until last week.

Can you help him recover the documents by factoring this large number for him?

26390 85015 23339 22027 40949 38630 97432 59521 51779 38861 43240 989

Please submit your answer by entering the digit sum of the smallest prime factor.
