What Is The HCF Of 9 And 11?

What is the HCF of 9 and 12?

Greatest common factor (GCF) of 9 and 12 is 3.

We will now calculate the prime factors of 9 and 12, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 9 and 12..

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”

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 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 9 and 15?

Greatest common factor (GCF) of 9 and 15 is 3. We will now calculate the prime factors of 9 and 15, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 9 and 15.

What is the HCF of 9 and 45?

The factors of 45 are 45, 15, 9, 5, 3, 1. The common factors of 9 and 45 are 9, 3, 1, intersecting the two sets above. In the intersection factors of 9 ∩ factors of 45 the greatest element is 9. Therefore, the greatest common factor of 9 and 45 is 9.

What is the HCF of 5 and 25?

The hcf(25,35) is 5 .

How is HCF calculated?

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 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 0 and 6?

The highest common factor of 0 and 6 is “undefined”.

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 36 and 84?

23. Find the highest common factor of 36 and 84. H.C.F. = 22 x 3 = 12.

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 HCF of 9?

Factors of 9 = 1, 3 and 9. Therefore, common factor of 6 and 9 = 1 and 3. Highest common factor (H.C.F) of 6 and 9 = 3. Therefore, 3 is H.C.F.

What is the HCF of 30?

Factors of 30 (Thirty) = 1, 2, 3, 5, 6, 10, 15 and 30. Factors of 24 (Twenty four) = 1, 2, 3, 4, 6, 8, 12 and 24. Therefore, common factor of 30 (Thirty) and 24 (Twenty four = 1, 2, 3, and 6. Highest common factor (H.C.F) of 30 (Thirty) and 24 (Twenty four = 6.
