@dalias @christopherkunz @49016 except 156, they're all multiples of two prime numbers

EDIT: I saw a different list than this one in the OPs toot. This list has a number of items that aren't what I said. Sorry for jumping the gun

237 = 3 * 79
230 = 2 * 5 * 23
155 = 5 * 31
115 = 5 * 23
66 = 2 * 3 * 11
65 = 5 * 13
156 = 2 * 2 * 3 * 13
