One of the simplest hashing algorithms involves dividing the primary key field by a particular .

Prime number

Explanation:

Hashing algorithm is a computer engineering term that describes a function that develops or transforms an inputs data value into a fixed-size length numeric value output. The output string is typically smaller in comparison with the input data.

However, one of the simplest hashing algorithms involves dividing the primary key field by a particular Prime Number. This is because there is a high tendency of avoiding a crash while also acquiring a distinct output.

Hence, the correct answer is PRIME NUMBER.

i'm so sorry that's not a question and this isn't an answer
