Sum Squared Divisors, Get Number (Posted on 2007-05-03) Difficulty: 4 of 5
Determine all possible positive whole numbers t such that t is equal to the sum of the squares of its four smallest positive divisors including 1.

For example, 1, 2, 4 and 5 are the four smallest positive divisors of 40.
But, 12 + 22 + 42+ 52 = 46. So, t = 40 is NOT a valid solution.
