The number that doesn't belong in the sequence is 123. The pattern among the other numbers is that they are all prime numbers, specifically 3, 31, and 27 (which is a prime cube). However, 123 is not a Prime number as it can be divided by 3 and 41.

27 doesn't belong because it rounds up and all the other numbers round down.
