Any product of odd numbers is odd.
The sum of two odd numbers is even.

3^11 and 5^13 are both the product of odd numbers,
so they are both odd

So 3^11 + 5^13 is the sum of two odd numbers and
is therefore even.

Any even number is divisible by 2. Therefore 2 is the smallest prime
that divides 3^11 + 5^13. [In fact, 2 is the
smallest prime]

[ 3^11 + 5^13 = 1220880272 = 24*47*107*15173, but we don't need that!)
