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.
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.

The prime factors of 102 are: 2, 3, 17
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 45 and 102 are both composite.
To dial the USA or Canada, you must prefix the 10-digit national number with "001". For example, US number 929-102-0021 would become 001 929 102 0021.
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
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
