How come 0 a factor of itself?
As per ChatGPT, No, 0 is not considered a factor of itself. A factor of a number is a number that divides it exactly, without leaving a remainder. For any non-zero number, a factor is a positive integer that divides the number evenly.
For 0, the concept of being a factor doesn’t apply in the usual sense because any non-zero number multiplied by 0 equals 0. However, 0 divided by any non-zero number is undefined, so we don’t say that 0 is a factor of itself. Factors are typically discussed in the context of positive integers or sometimes in negative integers, but 0 is an exception and does not fit the standard definition of a factor.
