## What is the GCF of 18 and 27?

Example: Find the GCF of 18 and 27 The factors of 18 are 1, 2, 3, 6, 9, 18.

The factors of 27 are 1, 3, 9, 27.

The common factors of 18 and 27 are 1, 3 and 9.

The greatest common factor of 18 and 27 is 9..

## 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 GCF of 24?

Answer and Explanation: The GCF of 24 and 36 is 12. ‘GCF’ means ‘greatest common factor’. That’s the greatest, or largest, factor that the two numbers share.

## What is the GCF of 25 and 15?

5The Greatest Common Factor of 15and25 is 5. (the number itself and 1 do not count). The factor(s) of 25 is 5 . After all, it is a square number.

## What is the LCM of 18 and 3?

Least common multiple (LCM) of 3 and 18 is 18.

## What is the highest common factor of 9 12 and 15?

The factors of 12 are : 1, 2, 3, 4, 6, 12. The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.

## What is the GCF of 15?

The prime factors they have in common are 3 x 5. 3 x 5 = 15. The greatest common factor is 15. When two numbers have no prime factors in common, their greatest common factor is 1.

## What is the GCF of 9 and 18?

Greatest common factor (GCF) of 9 and 18 is 9. We will now calculate the prime factors of 9 and 18, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 9 and 18.

## What is the HCF of 9 and 30?

Greatest common factor (GCF) of 9 and 30 is 3. We will now calculate the prime factors of 9 and 30, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 9 and 30.

## What is the GCF of 9 and 36?

The common factors of 9 and 36 are 9, 3, 1, intersecting the two sets above. In the intersection factors of 9 ∩ factors of 36 the greatest element is 9. Therefore, the greatest common factor of 9 and 36 is 9.

## What is the GCF of 9 and 15?

Greatest common factor (GCF) of 9 and 15 is 3.

## What is the GCF and LCM of 9 and 15?

Least common multiple (LCM) of 9 and 15 is 45.

## What is the GCF of 15 and 30?

Greatest common factor (GCF) of 15 and 30 is 15.

## What is the LCM of 3 15 and 9?

The LCM of 3, 9 and 15 is 45.

## 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 LCM for 15 and 10?

Least common multiple (LCM) of 10 and 15 is 30.

## What is the GCF of 100 and 15?

The common factors of 15 and 100 are 5, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 100 the greatest element is 5. Therefore, the greatest common factor of 15 and 100 is 5.

## 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.
