## What is the HCF of 15 and 20?

We found the factors and prime factorization of 15 and 20.

The biggest common factor number is the GCF number.

So the greatest common factor 15 and 20 is 5..

## 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 factor of 10 and 5?

The gcf of 5 and 10 can be obtained like this: The factors of 5 are 5, 1. The factors of 10 are 10, 5, 2, 1. The common factors of 5 and 10 are 5, 1, intersecting the two sets above.

## What is the HCF of 5 and 25?

The hcf(25,35) is 5 .

## 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 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 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 5 and 20?

The common factors of 5 and 20 are 5, 1, intersecting the two sets above. In the intersection factors of 5 ∩ factors of 20 the greatest element is 5. Therefore, the greatest common factor of 5 and 20 is 5.

## What is the HCF of 5 and 12?

The factors of 12 are 12, 6, 4, 3, 2, 1. The common factors of 5 and 12 are 1, intersecting the two sets above. In the intersection factors of 5 ∩ factors of 12 the greatest element is 1. Therefore, the greatest common factor of 5 and 12 is 1.

## What is the GCF of 5x and 10?

The biggest common factor number is the GCF number. So the greatest common factor 5 and 10 is 5.

## What is the GCF of 15 and 10?

We found the factors and prime factorization of 10 and 15. The biggest common factor number is the GCF number. So the greatest common factor 10 and 15 is 5.

## What is the HCF of 12 and 24?

We found the factors and prime factorization of 24 and 12. The biggest common factor number is the GCF number. So the greatest common factor 24 and 12 is 12.
