What are the even prime numbers?
There is only one even prime number: 2. All other even numbers are multiples of 2, and thus are not prime.
Can a prime number be a multiple?
All numbers are multiples.
Which two multiples of 13 are co-prime number?
No multiples of the same number greater than one can be co-prime, since they will both have that number as a factor.
Can you explain to me why the multiples of any number other than 1 are not prime numbers?
Sure! The multiples of a number other than 1 will always have at least three factors: 1, the number itself, and the multiple. This means they are not prime numbers, as prime numbers only have two factors: 1 and the number itself. For example, the multiples of 2 will always be divisible by 2, making them composite numbers rather than prime.
How many even prime numbers are there from 1 to 100?
The only even prime number (not only from 1 to 100, but in general) is 2. All other even numbers are multiples of 2, and therefore, by definition, not prime numbers.
