A Prime number is a positive whole number (a positive integer) that has exactly two unique positive divisors, 1 and the number itself.
In each it is best if you start by finding the prime factors of each number.
7 is a prime number!
167 is a prime number.
109 is a prime number.
Take your pick! Which one do you want it to be? 75: It is the only number that is the product of three (an odd number of) prime factors. 360: It is the only number with three different prime factors. 100: It is the only number that is the product of two pairs of two prime factors. 25: It is the only number that is a square of a prime. 51: It is the only semi-prime. 4000: It is the only number that is a product of 8 prime factors. So, given these unique characteristics, it is always possible to define a set in such a way that the stated characteristic makes that number the "odd one out".

It has only two factors: ' 1 ' and itself.No other whole numbers divide into it equally.
Each number is either itself a prime number, or it can be separated into smaller prime numbers. A prime number is a number that has no smaller factors. Factorization into prime factors is unique, except for the order of the factors.

A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies

A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
101 is a prime number. The only factor of 101 is itself and 1.prime
