Question

What are co-prime and twin prime numbers

Answer 1

Co-prime numbers:

Two numbers are said to be co-primes if they do not share any common divisor except for 1. For example, 9 and 10 are co-primes as number 9 has factors 1,3,9 and 10 has 1,2,5,10. Here, only 1 is common.

So, these two are co-prime numbers.

Twin-prime numbers:

Two prime numbers are said to be twin-prime if there difference is 2. For example, number 3 and 5, 17 and 19. Hope this helps!!
