## How is HCF calculated?

The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

## What is the HCF of 8 and 9 and 25?

H.C.F of 8, 9 and 25 = 1 [HCF(Highest Common Factor) of two or more numbers= Product of the smallest Power of each common prime factor involved in the numbers.]

## 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 18 and 60?

6The common factors of 18 and 60 are 6, 3, 2, 1, intersecting the two sets above. In the intersection factors of 18 ∩ factors of 60 the greatest element is 6. Therefore, the greatest common factor of 18 and 60 is 6.

## What is the HCF of 8?

For example, a common factor of 8 and 10 is 2, as 2 is a factor of 8, and 2 is also a factor of 10. The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one. For example, 8 and 12 have common factors of 1, 2 and 4. The highest common factor is 4.

## What is the HCF of 5 and 25?

The hcf(25,35) is 5 .

## What is the HCF of 18 and 48?

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.

## What is the HCF of 4 and 5?

We found the factors and prime factorization of 4 and 5. The biggest common factor number is the GCF number. So the greatest common factor 4 and 5 is 1.

## 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?

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 15 and 30?
