Re: 53, 59, 60, 61, 65, 66, 67, 68, 71, 73, 74, 76, 79, 83, 89, 91, 93, 97
That is easy. All these number are prime. That means they are only divisible by one and itself!
Re: k i lied, all i need is
60 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
65 = 1, 5, 13, 65
66 = 1, 2, 3, 6, 11, 22, 33, 66
68 = 1, 2, 4, 17, 34, 68
74 = 1, 2, 37, 74
76 = 1, 2, 4, 19, 38, 76
91 = prime, so only 1 and 91 (itself)
93 = prime, so only 1 and 93 (itself)
