Quick Answer: What Is The HCF Of 12 And 15?

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 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 18 and 36?

The common factors of 18 and 36 are 18, 9, 6, 3, 2, 1, intersecting the two sets above. In the intersection factors of 18 ∩ factors of 36 the greatest element is 18. Therefore, the greatest common factor of 18 and 36 is 18.

What is the HCF of 9 and 12?

3The biggest common factor number is the GCF number. So the greatest common factor 9 and 12 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 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 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.

What is the HCF of 5 and 25?

The hcf(25,35) is 5 .

What is the HCF of 13 23 and 14?

Given that other two factors in the LCM are 13 and 14. We have seen that the numbers are (23 × 13) and (23 × 14). Clearly we get HCF as 23 and the factors in the LCM as 13, 14 and 23.

What are the HCF of 12 and 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 13 and 15?

gcf, hcf, gcd (13; 15) = 1: greatest (highest) common factor (divisor), calculated. Coprime numbers (relatively prime). Numbers have no common prime factors.

What is the HCF of 18 and 48?

We found the factors and prime factorization of 18 and 48. The biggest common factor number is the GCF number. So the greatest common factor 18 and 48 is 6.

What is the HCF of 12 and 24?

We found the factors and prime factorization of 24 and 12. The biggest common factor number is the GCF number. So the greatest common factor 24 and 12 is 12.

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.

What is the HCF of 4 and 6?

We found the factors and prime factorization of 4 and 6. The biggest common factor number is the GCF number. So the greatest common factor 4 and 6 is 2.

What is the HCF of 12 and 18?

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].

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 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.

How do you find the HCF of 16?

Find the H.C.F. of 16, 18 and 24. Step I: First we consider the first two numbers and follow the same step 1, 2 and 3 of the above example. Step II: The H.C.F. of the first two numbers which is 2 becomes the divisor and the third number 24 becomes the dividend.

What is the HCF of 16 and 18?

Greatest common factor (GCF) of 18 and 16 is 2.

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.
