## What is the GCF of 3 and 6?

The prime factors and multiplicities 3 and 6 have in common are: 3.

3 is the gcf of 3 and 6.

gcf(3,6) = 3..

## What is the GCF of 2 and 3?

Multiply the circled numbers together. This is the greatest common factor! In the example, gcf(18,36,90)=2⋅3⋅3=18 gcf ( 18 , 36 , 90 ) = 2 ⋅ 3 ⋅ 3 = 18 .

## What is the GCF of 12 and 16?

The factors of 12 include: 1, 2, 3, 4, 6, and 12. Thus, the common factors of 16 and 12 are: 1, 2, and 4. Often in math problems, it can be desirable to find the greatest common factor of some given numbers. In this case, the greatest common factor is 4.

## 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 for 15 and 6?

3Greatest Common Factor of 6 and 15 Greatest common factor (GCF) of 6 and 15 is 3.

## 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 HCF of 4 and 5?

The highest common factor of two numbers is the largest whole number which is a factor of both. This can sometimes also be called the Greatest Common Factor (GCF). Factors are whole numbers we can multiply together to get another number, for example, 4 and 5 are factors of 20 because 4 x 5 = 20.

## 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 GCF of 15 and 9?

We found the factors and prime factorization of 9 and 15. The biggest common factor number is the GCF number. So the greatest common factor 9 and 15 is 3.

## 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 GCF of 12 and 18?

In terms of numbers, the greatest common factor (gcf) is the largest natural number that exactly divides two or more given natural numbers. Example 1: 6 is the greatest common factor of 12 and 18.

## What is the GCF of 15 and 20?

Greatest common factor (GCF) of 15 and 20 is 5.

## 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 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 15 and 6?

Greatest common factor (GCF) of 6 and 15 is 3. We will now calculate the prime factors of 6 and 15, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 6 and 15.

## What is the GCF 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 GCF of 4 and 6?

2Greatest common factor (GCF) of 4 and 6 is 2.

## 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.
