Just set $a=b=2^{n-2}$ for any $n \in \mathbb{N}$ where $n \geqslant 2$

One line question, one line answer!

Let $\ a,b,c\$ be integers with $\ 0<a<b<c\$ and let $\ m\$ be the smallest non-negative integer such that $$a^m+b^m+c^m$$ is composite. Define $$f(a,b,c)=m-1$$ Hence $\ f(a,b,c)\$ is the largest non-negative integer $\ m\$ such that $$a^k+b^k+c^k$$ is prime for $\ k=0,\cdots ,m\$. Since f...

@Haran Want to help factoring some integers ?

I don't have the software for factoring large integers
I don't think I will be allowed to download such software either
