contract puzzle issue

[Ducatislave]

contract-760130.cct on the silver-helix asks : "What is the largest prime factor of 95092558?"
the answer i come up with is 19. however the game returns that it is wrong.
I did it on paper the old fashioned way first, then when it said my answer was incorrect i double checked it against 2 different AI frameworks and all 3 of us came up with the same answer. is there an element of the puzzle that i am missing?

thank you

Hello!

I don't know how did you do your math, but 19 doesn't divide 95092558.

Cheers.
