Quick Answer: What Is The HCF Of 20?

What is the HCF of 17 and 5?

The biggest common factor number is the GCF number.

So the greatest common factor 5 and 17 is 1..

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 HCF of 5 and 25?

The hcf(25,35) is 5 .

What is the HCF of 12?

HCF Example 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 HCF of 10 15?

Find the highest common factor (H.C.F) of 15 and 10. Factors of 10 = 1, 2, 5 and 10. Therefore, common factor of 15 and 10 = 1 and 5. Highest common factor (H.C.F) of 15 and 10 = 5.

What is HCF of two numbers?

HCF of two numbers is the highest common number, which is available in both the numbers. HCF or highest common factor is the factor of any two or more numbers, which are common among them. … Sometimes, it is also called the greatest common factor (GCF) or greatest common divisor (GCD).

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 15?

Factors of 15 (Fifteen) = 1, 3, 5 and 15. Factors of 35 (Thirty five) = 1, 5, 7 and 35. Therefore, common factor of 15 (Fifteen) and 35 (Thirty five) = 1 and 5. Highest common factor (H.C.F) of 15 (Fifteen) and 35 (Thirty five) = 5.

What is the HCF of 5 and 15?

We found the factors and prime factorization of 5 and 15. The biggest common factor number is the GCF number. So the greatest common factor 5 and 15 is 5.

What is the GCF of 20 30?

The numbers 20 and 30 have the factors 2 and 5 in common. Next, multiply the common factors to find the GCF. If there is only one common factor, there is no need to multiply. The GCF of 20 and 30 is 10.

What is the HCF of 16 and 24?

8Consider 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.

How do you explain HCF?

The Highest Common Factor (H.C.F) of two (or more) numbers is the largest number that divides evenly into both numbers. In other words the H.C.F is the largest of all the common factors. The common factors or of 12 and 18 are 1, 2, 3 and 6. The largest common factor is 6, so this is the H.C.F. of 12 and 18.

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.

What is the HCF of 20 and 24?

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 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.

What is the HCF of 56?

56 = 1 × 2 × 2 × 2 × 7. Common factor of 12 and 56 = 1, 2, 2. Highest common factor of 12 and 56 = 2 × 2 = 4.

What is the HCF of 20 and 30?

We found the factors and prime factorization 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 highest common factor for 20?

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 10 and 20?

Greatest common factor (GCF) of 10 and 20 is 10. We will now calculate the prime factors of 10 and 20, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 10 and 20.

What is the HCF of 5 and 6?

The prime factorization of 6 is: 2 x 3. The prime factors and multiplicities 5 and 6 have in common are: 1. 1 is the gcf of 5 and 6. gcf(5,6) = 1.

What is the HCF of 96 and 72?

24Answer. So, H.C.F of 96 and 72 is 24.
