Dwelling upon the triangular numbers

  1. Feb 20, 2009 #1
    Each of Hank, Jim and Larry chose a different five-digit triangular number whose digits had the pattern DWELL, where each different letter represents a different base-10 digit. Jim's triangular number had no digit in common with either Hank's or Larry's.

    Determine the numbers chosen by each of the three individuals.

    Note: None of the numbers can contain any leading zero.

    There are two solutions
    Jim = 27966
    Hank = 15400
    Larry = 58311


    Jim = 27966
    Hank = 58311
    Larry = 15400
    I used brute force to solve this.
