2, 3 and 17
No
A prime number is divisible only by itself - 102 is divisible by 2 and 51 so it is not a prime.
102 = 2 * 3 * 17
It cannot be a prime number because it is even. The only prime number that is even is the number 2. 102 is a composite number, the product of the integers 2 x 3 x 17.
102 is a composite number because it has more than 2 factors
No, 102 and 321 are not relatively prime. Relatively prime numbers only have the number 1 as a common factor. 102 and 321 have other common factors, like 3.

102
17 is the largest number that evenly divides both 102 and 85.
100 is divisible by 1, 2, and 5. 1 is not itself a prime number; 101 is a prime; 102/2 =51 102/3 =34 102/17=6
To identify whether a number is prime or composite, look at its factors. A prime number has exactly two factors: one and itself. A composite number has more factors and can be written as the product of prime numbers. For example: Factors of 17: 1 and 17 so 17 is prime. Factors of 102: 1, 2, 3, 6, 17, 34, 51 and 102 so 102 is composite. It can be expressed as the product of prime numbers by prime factoring: 2 x 3 x 17
317 is a prime number
