What are all co prime numbers from 1-500?

Are co-prime numbers and twin prime numbers the same?
No - co-prime numbers are pairs of numbers which share no positive integer factors apart from 1. Twin prime numbers are a pair of prime numbers with a difference of 2.
What is it called when the greatest common factor is 1?
Such numbers are relatively prime, or co-prime.
What is the co-prime numbers?
Two numbers are considered to be co-prime if they share no common prime factors, that is, if their GCF is 1.
What is a co-prime factor?

What is the greatest common factor of 11 and 56?
The GCF of 11 and 56 is 1. Since 11 is prime and is not a factor of 56, the numbers are co-prime, and have no other common factor except 1.
What are all co prime numbers from 1 500?
It's an enormous list; we wouldn't be able to get them all. All of the prime numbers in that range are co-prime with each other. The composite numbers, as long as they aren't multiples of the primes, are co-prime with the primes. The square numbers are co-prime with each other and quite a few of the composite numbers are co-prime with each other. If you could narrow the range, we could be more specific.
