## What is 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 GCF of 3 and 9?

Greatest common factor (GCF) of 3 and 9 is 3.

## What is the GCF of 2 and 6?

Greatest common factor (GCF) of 2 and 6 is 2. We will now calculate the prime factors of 2 and 6, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 2 and 6.

## What is the HCF of 12 and 18?

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 16 and 24?

8Consider 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 2 and 3?

182 and 3 are the prime number common to all given numbers. Step3: Product of the numbers taken. So 18 is the GCD (Greatest Common Divisor) of the numbers.

## What is the greatest common factor of 3 and 6?

While 3 and 6 share a factor, and 6 and 8 share a factor, there is no prime factor that all three of them share. Since 1 divides into everything, then the greatest common factor in this case is just 1. When 1 is the GCF, the numbers are said to be “relatively” prime; that is, they are prime, relative to each other.

## What is the GCF of 15 and 42?

The factors of 42 are 42, 21, 14, 7, 6, 3, 2, 1. The common factors of 15 and 42 are 3, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 42 the greatest element is 3. Therefore, the greatest common factor of 15 and 42 is 3.

## What is the GCF of 33 and 15?

3Greatest common factor (GCF) of 15 and 33 is 3.

## What is the GCF of 4 and 6?

We found the factors and prime factorization of 4 and 6. The biggest common factor number is the GCF number. So the greatest common factor 4 and 6 is 2.

## What is the GCF calculator?

What is the Greatest Common Factor? The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder. For example, for the set of numbers 18, 30 and 42 the GCF = 6.

## What is the GCF of 7/15 and 21?

The common factors for 7,15,21 7 , 15 , 21 are 1 . The GCF (HCF) of the numerical factors 1 is 1 .

## What is the GCF of 12 and 30?

Earlier we found that the Common Factors of 12 and 30 are 1, 2, 3 and 6, and so the Greatest Common Factor is 6. The Greatest Common Factor of 12 and 30 is 6.

## What is the GCF of 24 and 18?

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 GCF of 7 and 28?

Answer and Explanation: The GCF of 7 and 28 is 7. The greatest common factor is the greatest number that is a factor for both the numbers you’re comparing.

## What’s the GCF of 18 and 6?

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

## What is the GCF of 36 63?

The prime factorization of 63 is: 3 x 3 x 7. The prime factors and multiplicities 36 and 63 have in common are: 3 x 3. 3 x 3 is the gcf of 36 and 63. gcf(36,63) = 9.

## What do 15 and 21 have in common?

Greatest common factor (GCF) of 15 and 21 is 3.
