The hcf(25,35) is 5 ..

What is the HCF of 36 and 48?

12Greatest common factor (GCF) of 36 and 48 is 12. We will now calculate the prime factors of 36 and 48, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 36 and 48.

What is the HCF of 15 and 30?

The common factors of 15 and 30 are 1, 3, 5, and 15. The greatest common factor is 15.

What is the HCF of 4 and 8?

Greatest common factor (GCF) of 4 and 8 is 4. We will now calculate the prime factors of 4 and 8, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 4 and 8.

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 20?

Example: Find the GCF of 20, 50 and 120 The common factors of 20, 50 and 120 are 1, 2, 5 and 10. (Include only the factors common to all three numbers.) The greatest common factor of 20, 50 and 120 is 10.

What is the HCF of 16?

The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12 and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.

What is the HCF of 7 and 4?

The factors of 7 are 7, 1. The common factors of 4 and 7 are 1, intersecting the two sets above. In the intersection factors of 4 ∩ factors of 7 the greatest element is 1. Therefore, the greatest common factor of 4 and 7 is 1.

What is the HCF of 15 and 45?

We found the factors and prime factorization of 15 and 45. The biggest common factor number is the GCF number. So the greatest common factor 15 and 45 is 15.

What is the HCF of 4 and 16?

Greatest common factor (GCF) of 4 and 16 is 4. We will now calculate the prime factors of 4 and 16, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 4 and 16.

What is the HCF of 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 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 HCF formula?

Greatest Common Measure(GCM) and Greatest Common Divisor(GCD) are the other terms used to refer HCF. Example : HCF of 60 and 75 = 15 because 15 is the highest number which divides both 60 and 75 exactly. We can find out HCF using prime factorization method or by dividing the numbers or division method.

What is the HCF of 4 and 5?

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 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 15 and 35?

5Answer and Explanation: The greatest common factor of 35 and 15 is 5. The ‘greatest common factor’ is sometimes called the ‘GCF. ‘ The GCF of 15 and 35 is the greatest…

What is the highest common factor of 4 and 12?

Greatest common factor (GCF) of 4 and 12 is 4.

What is the HCF of 5 and 7?

gcf, hcf, gcd (5; 7) = 1: greatest (highest) common factor (divisor), calculated. Coprime numbers (relatively prime). Numbers have no common prime factors.

What is the HCF of 12?

Find the highest common factor (H.C.F) of 12 and 18. Factors of 12 = 1, 2, 3, 4, 6 and 12. 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].
