How do I solve this? NO guess and check.

bruteforce would be good here tbf

like going for the largest prime number < 173 then going through the smallest until 2 fit

#

since they are consecutive, you can first set an upper bound on the largest prime found.

#

or an estimate of the largest prime found.

#

actually I'm not sure how well this holds, let me cross that out. sorry.

53,57,59 gets 169

#

this is the closest

#

57 is not a prime.

#

57 = 3 x 19.

#

it is a Grothendieck prime I suppose. KEK

#

but you're rather close to the actual triple.

it's a kind of funny term to describe a number that is not a prime, but is 3 times a prime.
57 is the smallest amongst them for some reason. not too relevant here.
