What are numbers called with only one factor?

Answer 1

Numbers with only one factor are called prime numbers. A Prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. Examples of prime numbers include 2, 3, 5, 7, 11, and so on. These numbers have only two factors: 1 and the number itself.

A number with only those two factors and no others is called a "prime" number.
