## What is the HCF of 9 and 11?

gcf, hcf, gcd (9; 11) = 1: greatest (highest) common factor (divisor), calculated.

Coprime numbers (relatively prime).

Numbers have no common prime factors..

## What is the HCF of 15?

Factors of 15 (Fifteen) = 1, 3, 5 and 15. Factors of 35 (Thirty five) = 1, 5, 7 and 35. Therefore, common factor of 15 (Fifteen) and 35 (Thirty five) = 1 and 5. Highest common factor (H.C.F) of 15 (Fifteen) and 35 (Thirty five) = 5.

## What is the HCF of 20 and 30?

The numbers 20 and 30 have the factors 2 and 5 in common. Next, multiply the common factors to find the GCF. If there is only one common factor, there is no need to multiply. The GCF of 20 and 30 is 10.

## What is the HCF of 12 and 16?

The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12 and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.

## What is the HCF of 15 and 20?

5Greatest common factor (GCF) of 15 and 20 is 5. We will now calculate the prime factors of 15 and 20, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 20.

## What is the HCF of 12 and 15?

The factors of 12 are : 1, 2, 3, 4, 6, 12. The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.

## What is the HCF of 16?

Consider the highest common factor of 16 and 24 again. The common factors are 1, 2, 4 and 8. So, the highest common factor is 8.

## What is the HCF of 18 and 24?

We found the factors and prime factorization of 18 and 24. The biggest common factor number is the GCF number. So the greatest common factor 18 and 24 is 6.

## What is the highest common factor of 9?

Finding the Greatest Common FactorTwo NumbersFactorsGreatest Common Factor9 and 129: 1, 3, 9 12: 1, 2, 3, 4, 6, 123

## Whats the HCF of 12 and 36?

We found the factors and prime factorization of 12 and 36. The biggest common factor number is the GCF number. So the greatest common factor 12 and 36 is 12.

## What is the HCF of 12?

Find the highest common factor (H.C.F) of 12 and 18. Factors of 12 = 1, 2, 3, 4, 6 and 12. 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].

## What is the HCF of 7 and 11?

Greatest common factor (GCF) of 7 and 11 is 1. We will now calculate the prime factors of 7 and 11, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 7 and 11.

## What is the HCF of 9 and 13?

The common factors of 13 and 9 are 1, intersecting the two sets above. In the intersection factors of 13 ∩ factors of 9 the greatest element is 1. Therefore, the greatest common factor of 13 and 9 is 1.

## What is the HCF of 5 and 7?

gcf, hcf, gcd (5; 7) = 1: greatest (highest) common factor (divisor), calculated. Coprime numbers (relatively prime). Numbers have no common prime factors.

## What is the HCF of 5 and 25?
