The prime factorization of 36 is: 2 x 2 x 3 x 3. The prime factors and multiplicities 18 and 36 have in common are: 2 x 3 x 3. 2 x 3 x 3 is the gcf of 18 and 36. gcf(18,36) = 18.

## 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 GCF of 18 and 54?

The prime factors and multiplicities 18 and 54 have in common are: 2 x 3 x 3. 2 x 3 x 3 is the gcf of 18 and 54. gcf(18,54) = 18.

## What is the HCF of 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 GCF of 17 and 23?

We found the factors and prime factorization of 17 and 23. The biggest common factor number is the GCF number. So the greatest common factor 17 and 23 is 1.

## What are the factors of 18 and 36?

The gcf of 18 and 36 can be obtained like this: The factors of 18 are 18, 9, 6, 3, 2, 1. The factors of 36 are 36, 18, 12, 9, 6, 4, 3, 2, 1. The common factors of 18 and 36 are 18, 9, 6, 3, 2, 1, intersecting the two sets above.

## What is the GCF of 45 and 18?

Answer and Explanation: The ‘GCF’ is the ‘greatest common factor’ that is shared between two numbers. Between 18 and 45, the GCF is 9, and here’s how you know.

## What is the GCF of 18 and 30?

Greatest common factor (GCF) of 18 and 30 is 6. We will now calculate the prime factors of 18 and 30, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 18 and 30.

## 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 HCF of 30?

Factors of 30 (Thirty) = 1, 2, 3, 5, 6, 10, 15 and 30. Factors of 24 (Twenty four) = 1, 2, 3, 4, 6, 8, 12 and 24. Therefore, common factor of 30 (Thirty) and 24 (Twenty four = 1, 2, 3, and 6. Highest common factor (H.C.F) of 30 (Thirty) and 24 (Twenty four = 6.

## What’s the GCF of 18 and 9?

We found the factors and prime factorization of 9 and 18. The biggest common factor number is the GCF number. So the greatest common factor 9 and 18 is 9.

## What is the GCF of 52 and 28?
