What is the HCF of two Coprime numbers?
In number theory, two integers a and b are coprime, relatively prime or mutually prime if the only positive integer that evenly divides (is a divisor of) both of them is 1.
One says also a is prime to b or a is coprime with b..
Two successive integers are always coprime. For eg: (2,3), (11,12), (99,100) and so on; they have 1 as their HCF.
Factors of 18 = 1, 2, 3, 6, 9 and 18. Therefore, common factor of 12 and 18 = 1, 2, 3 and 6. Highest common factor (H.C.F) of 12 and 18 = 6 [since 6 is the highest common factor].
The confusion begins with this definition a person might give of "prime": a prime number is a positive whole number that is only divisible by 1 and itself. … The number 1 is divisible by 1, and it's divisible by itself. But itself and 1 are not two distinct factors.
Final Step: Biggest Common Factor Number We found the factors and prime factorization of 18 and 48. The biggest common factor number is the GCF number. So the greatest common factor 18 and 48 is 6.
Common factors of 15 and 18 are 1 and 3. Since the given set of numbers have more than one factor as 3 other than factor as 1. So, 15 and 18 are not coprime numbers.

They are 1, 5, 7, and 11. There are 8 positive integers less than 15 and co- prime with 15. They are 1, 2, 4, 7, 8, 11, 13 and 14.
Factors of 18 are 1, 2, 3, 6, 9 and 18. Factors of 35 are 1, 5, 7 and 35. Therefore, 1 is the only common factor of 18 and 35. It means that 18 and 35 are co-prime.
factors of 18: 1,2,3,6,9,18. factors of 35: 1,5,7,35. yes, they are co-prime numbers because only one factor is common that is 1.
Two numbers are relatively prime if the only common positive factor of the two numbers is one. … Every integer (except zero) divides zero and the only positive factor of one is one. Thus, the only common positive factor of zero and one is one.
Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd. Two methods used below.12 = 22 × 3; 12 is not a prime, is a composite number;17 is a prime number, it cannot be broken down to other prime factors;
The greatest common factor is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.
The factors of 31 are 1 and 31 and the factors of 93 are 1, 3 and 31. Here 31 and 93 have two common factors: they are 1 and 31. Hence, their HCF is 31 and they are not co-prime.
For example, 2 and 3 are two prime numbers. Factors of 2 are 1, 2, and factors of 3 are 1, 3. The only common factor is 1 and hence they are co-prime. Any two successive numbers/ integers are always co-prime: Take any consecutive numbers such as 2, 3, or 3, 4 or 5, 6, and so on; they have 1 as their HCF.
9 and 10 are the coprime numbers .
1The HCF of two co-prime numbers is 1.
