Quick Answer: What Is The HCF Of 12 And 8?

What is the highest common factor of 8 and 12?

For example, 8 and 12 have common factors of 1, 2 and 4.

The highest common factor is 4..

What is the HCF of 12 and 7?

Greatest common factor (GCF) of 7 and 12 is 1. We will now calculate the prime factors of 7 and 12, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 7 and 12.

What is the HCF of 24 and 12?

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.

How do you calculate HCF?

The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

What is the HCF of 7 and 5?

35lowest common Denominator (LCD) of 5 and 7= 35 We get factors of 5,7 numbers by finding numbers that can divide 5,7 without remainder or alternatively numbers that can multiply together to equal the target number being converted.

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 12 and 30?

Earlier we found that the Common Factors of 12 and 30 are 1, 2, 3 and 6, and so the Greatest Common Factor is 6. The Greatest Common Factor of 12 and 30 is 6.

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 meant by HCF?

The greatest number that is a factor of two (or more) other numbers. When we find all the factors of two or more numbers, and some factors are the same (“common”), then the largest of those common factors is the Greatest Common Factor. Abbreviated “GCF”. Also called “Highest Common Factor”

Why do we calculate HCF?

In case of HCF, if some remainders are given, then firstly those remainders are subtracted from the numbers given and then their HCF is calculated. … Sometimes in case of HCF questions, the required remainder is given and when the remainder is not given, in those cases you will generally have three numbers given.

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 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].

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 16 and 24?

8Example 21 Consider 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 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.
