Is good the title ?
Numbers that are equal to the sum of the squares of his first divisors
1, 130, 1860, 148840, 3039520
130 (1, 2, 5, 10) 1^2+2^2+5^2+10^2 = 1+4+25+100 = 130
1860 (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30)
148480 (1, 2, 4, 5, 8, 10, 16, 20, 29, 32, 40, 58, 64, 80, 116, 128, 145,

121, 157, 160, 176, 220, 242, 314, 352, 440, 484, 605, 628, 785, 880) 121,
