A set of numbers which do not have any other common factor except 1 are called as co-prime numbers.
For example:- 2 and 3 are co prime numbers as they only have 1 as common factor between them. Some other examples of co-prime numbers are 4 and 5, 6 and 7, 8 and 9 etc.
• All prime numbers are co-prime to each other.
• Any 2 consecutive integers are always co-prime.
• Sum of any two co-prime numbers is always co-prime with their product.
• 1 is co-prime with all numbers.
• a and b (natural numbers) are co-prime only if the numbers 2a-1 and 2b-1 are co-prime.
