To date, the largest number that has been factorised is 21.
The odds of achiving a quantum computer capable of factoring numbers by 2026 is 1/7 by 2031 1/2

Government responses
“There is an emerging consensus that the best practical approach to quantum security is to evolve current security applications and packet-based communication protocols towards adopting post-quantum public key cryptography.”CESG - 18th February 2016
“we recommend not making a significant expenditure to do so at this point but instead to prepare for the upcoming quantum resistant algorithm transition”NSA- 21st August 2015
