241

This number is a prime.

The smallest prime value (out of 14) resulting from the ninedigital fraction equation (A/B)^C + (D/E)^F + (G/H)^I, where the letters A to I represent any combination of the nine digits 1 through 9. Note that (6/3)^5 + (8/4)^7 + (9/1)^2 and (6/3)^7 + (8/4)^5 + (9/1)^2 are the only two distinct solutions for 241. [De Geest]
