A non-factor.
an uncommon factor which is any of the other factors that is not a common factor
A factor or a divisor.
In one sense, the opposite of the GCF could be the least common factor, but the least common factor of any set of positive integers is 1, so it's not very interesting.
a proper factor is a factor.

The noble gas configuration for cobalt (Co) is [Ar] 3d7 4s2, where [Ar] represents the electron configuration of argon. This notation indicates that cobalt has the same electron configuration as argon, with an additional 3d7 4s2 electron configuration specific to cobalt.
Cobalt has an electron configuration of 1S2 2S2 2P6 3S2 3P6 4S2 3d7 or. [Ar] 4S2 3d7
A non-factor.
The electron configuration for the +2 cation of cobalt (Co) is [Ar] 3d7. This is because cobalt has an atomic number of 27, which means its neutral configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d7. When it forms a +2 cation, it loses two electrons from its 4s subshell, resulting in the configuration [Ar] 3d7.
non-factor
The abbreviated electron configuration of cobalt is [Ar] 3d7 4s2.
The element with 27 protons is cobalt and its electron configuration is [Ar] 3d7 4s2.
I believe the opposite of a factor is a multiple.
