A positive integer X is defined as a bold number if precisely 8 of its distinct divisors sum to 3240. The total number of divisors of X may or may not be equal to 8.

Determine the minimum positive bold number.

(In reply to solution by Dej Mar)

But how did you arrive at this number (analysis, brute force, computer...?) and prove that it is the smallest positive value?
