## 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..

## 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 15 and 30?

The common factors of 15 and 30 are 1, 3, 5, and 15. The greatest common factor is 15.

## What is the HCF of 20?

Example: Find the GCF of 20, 50 and 120 The common factors of 20, 50 and 120 are 1, 2, 5 and 10. (Include only the factors common to all three numbers.) The greatest common factor of 20, 50 and 120 is 10.

## 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 5 10 15 and 20?

find gcf (5, 10, 15, . . . . , 25) = ? step 3The common prime factor or the product of all common prime factors between all integers is the highest common factor of this group of integers (5, 10, 15, 20 & 25).

## 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 20 30?

We found the factors and prime factorization of 20 and 30. The biggest common factor number is the GCF number. So the greatest common factor 20 and 30 is 10.

## What is the HCF of 5 and 25?

The hcf(25,35) is 5 .

## What is the HCF of 10 and 20?

Greatest common factor (GCF) of 10 and 20 is 10. We will now calculate the prime factors of 10 and 20, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 10 and 20.

## What is the HCF of 15 and 35?

5Answer and Explanation: The greatest common factor of 35 and 15 is 5. The ‘greatest common factor’ is sometimes called the ‘GCF. ‘ The GCF of 15 and 35 is the greatest…

## What is the HCF of 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 16 and 24?

8Example 21 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 highest common factor of 15 and 25?

Explanation: The Greatest Common Factor of 15and25 is 5. (the number itself and 1 do not count). The factor(s) of 25 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 5 and 15?

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

## What is the HCF of 18 24?
