Greatest common factor (GCF) of 20 and 24 is 4. We will now calculate the prime factors of 20 and 24, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 20 and 24.

## What is the HCF of 20 and 25?

Greatest Common Factors The largest common factor of two numbers is called their greatest common factor or highest common factor. Example: What is the greatest common factor of 20 and 25? The greatest common factor is 5.

## Whats the HCF of 18 and 30?

We found the factors and prime factorization of 30 and 18. The biggest common factor number is the GCF number. So the greatest common factor 30 and 18 is 6.

## What is HCF example?

HCF : The largest number that divides two or more numbers is the highest common factor (HCF) for those numbers. For example, consider the numbers 30 (2 x 3 x 5), 36 (2 x 2 x 3 x 3), 42 (2 x 3 x 7), 45 (3 x 3 x 5). 3 is the largest number that divides each of these numbers, and hence, is the HCF for these numbers.

## Whats the highest common factor of 20 and 30?

The biggest common factor number is the GCF number. So the greatest common factor 20 and 30 is 10.

## What is the HCF of 20?

For example, find the HCF of 20 and 35. The common factors of the given numbers are : 1,2,4,5,10,20. The greatest among all other numbers is 20, so it shall be the HCF of both the numbers.

## How do you find 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 are the factors of 20 30?
