A Nigerian professor, Opeyemi Enoch, has claimed he found the answer to Riemann Hypothesis – perhaps math’s most famous problem, which gone unsolved for 156 years.
Enoch(pictured), a lecturer with Federal University of Oye Ekiti (FUOYE) could be in line to win a $1million (£658,000) if the Clay Mathematics Institute confirmed that he has solved the problem. 
The hypothesis, which was proposed by mathematician Bernard Riemann in 1859, concerns the distribution of prime numbers. Enoch said he was persuaded by his students to tackle it, adding that he was not motivated by the money.
“The motivation was because my students trusted that the solution could come from me – not because the financial reward and that was why I started trying to solve the problem in the first place,” he told the BBC.
Riemann Hypothesis – a mathematical problem first proposed by German mathematician Bernhard Riemann in 1859.
It makes up one of the seven ‘millennium problems’, which are a set of problems proposed by the Clay Mathematics Institute in 2000.
So far only one of these has been solved – and the man who solved it in 2010, Grigori Perelman, actually declined the award, and the prize money.
