What are HCF of 12?

What are HCF of 12?

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].

How do you find HCF of 20?

To find the HCF of 20 and 25, we will find the prime factorization of the given numbers, i.e. 20 = 2 × 2 × 5; 25 = 5 × 5. ⇒ Since 5 is the only common prime factor of 20 and 25. Hence, HCF (20, 25) = 5.

What is a HCF of 12 and 18?

6
Answer: HCF of 12 and 18 is 6.

What is the HCF of 8/12 and 20?

As you can see when you list out the factors of each number, 4 is the greatest number that 8, 12, and 20 divides into.

What will be the HCF of 20 and 5?

To find the GCF of 5 and 20, we will find the prime factorization of the given numbers, i.e. 5 = 5; 20 = 2 × 2 × 5. ⇒ Since 5 is the only common prime factor of 5 and 20. Hence, GCF (5, 20) = 5.

What is the HCF of 12 14 and 20?

We found the factors of 12, 14, 20 . The biggest common factor number is the GCF number. So the Greatest Common Factor 12, 14, 20 is 2.

How to find the HCF of 12 and 20?

The HCF of 12 and 20 is 4. To calculate the HCF (Highest Common Factor) of 12 and 20, we need to factor each number (factors of 12 = 1, 2, 3, 4, 6, 12; factors of 20 = 1, 2, 4, 5, 10, 20) and choose the highest factor that exactly divides both 12 and 20, i.e., 4. How to Find the HCF of 12 and 20 by Long Division Method?

Which is the highest HCF for a given number?

HCF is the largest positive number that divides the given numbers, without any reminder. For example: highest common factor of 60 and 75 = 15 because 15 is the highest number which divides both 60 and 75 exactly. Similarly, HCF of 24 and 36 is 12, because the common factors of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12.

Which is the highest factor of 12 and 20?

There are 3 common factors of 12 and 20, that are 1, 2, and 4. Therefore, the highest common factor of 12 and 20 is 4. Prime factorization of 12 and 20 is (2 × 2 × 3) and (2 × 2 × 5) respectively.
