## Writeup

Upon Google, we found a tool called [Yafu](https://sourceforge.net/projects/yafu/), which can helps us to factor the semiprime number.

Using Yafu by entering the command `factor(22952152323332505688670761214671498225451684330137990990356473040741684014997701799009910066964917896400501477)`, we got our factors(63145347 and 3496275968) after short period of time!

Entering the factors into the website and we got our flag.
