## What is the HCF of 36?

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18 and 36. Therefore, common factor of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12. Highest common factor (H.C.F) of 24 and 36 = 12. Factors.

## What is the GCF of 28 and 70?

14Greatest common factor (GCF) of 28 and 70 is 14.

## What is the GCF of 38 and 57?

We found the factors and prime factorization of 38 and 57. The biggest common factor number is the GCF number. So the greatest common factor 38 and 57 is 19.

## What are the GCF of 36 and 90?

There is only one greatest common factor of 36 and 90 which is 18. There are also a number of common factors including 1, 2, 3, 6, 9, 18.

## What is the HCF of 10 and 30?

Greatest common factor (GCF) of 10 and 30 is 10. We will now calculate the prime factors of 10 and 30, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 10 and 30.

## 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 is the GCF of 12 and 36?

Answer and Explanation: The greatest common factor of 12 and 36 is 12. Here is how we do it: Common factors are factors that numbers have in common.

## What is the GCF of and 36?

1, 2, 3, 4, 6, 9, 12, 18, and 36. 1, 2, 3, 6, 9, 18, 27, and 54. Although the numbers in bold are all common factors of both 36 and 54, 18 is the greatest common factor. The second method to find the greatest common factor is to list the prime factors, then multiply the common prime factors.

## What is the HCF of 39 and 65?

13gcf, hcf, gcd (39; 65) = 13: greatest (highest) common factor (divisor), calculated. The numbers have common prime factors.

## What is the HCF of 36 and 28?

The GCF of 28 and 36 is 4.

## What is the HCF of 36 72 and 90?
