## How do you find the 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 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 GCF of 60 and 45?

The GCF of 45 and 60 is 15. Your first step to finding the GCF is to list all of the factors of both numbers. This way, you can see which factors…

## What is the HCF of 54 and 81?

Solution: Let’s find the HCF by prime factorization method. The HCF of 18, 54 and 81 is 9.

## What is the HCF of 56?

Answer. We found the factors and prime factorization of 42 and 56. The biggest common factornumber is the GCF number. So the greatest common factor 42 and 56 is 14.

## What is the HCF of 18 and 54?

The common factors of 18 and 54 are 18, 9, 6, 3, 2, 1, intersecting the two sets above. In the intersection factors of 18 ∩ factors of 54 the greatest element is 18. Therefore, the greatest common factor of 18 and 54 is 18.

## What is mean by HCF?

Highest Common FactorDefinition of LCM and HCF Highest Common Factor (HCF): The largest or greatest factor common to any two or more given natural numbers is termed as HCF of given numbers. Also known as GCD (Greatest Common Divisor). For example, HCF of 4, 6 and 8 is 2.

## What is the HCF of 81?

Factors of 81 are 1,3,9,27,81. Factors of 117 are 1,3,9,13,39,117. Factors of 189 are 1,3,7,9,21,27,63,189. Among these the highest common factor is 9. H.C.F of 81,117,189 is 9 [Ans]

## What is the HCF of 32 and 56?

8Greatest common factor (GCF) of 32 and 56 is 8.

## What is the HCF of 56 and 72?

We found the factors and prime factorization of 56 and 72. The biggest common factor number is the GCF number. So the greatest common factor 56 and 72 is 8.

## What is the HCF of 84?

We found the factors and prime factorization of 84 and 90. The biggest common factor number is the GCF number. So the greatest common factor 84 and 90 is 6.

## What is the HCF of 54?

54 = 2 × 27 = 2 × 3 × 9 = 2 × 3 × 3 × 3. 81 = 3 × 27 = 3 × 3× 9 = 3 × 3 × 3 × 3. 99 = 11 × 9 = 11 × 3 × 3. Factors common to all three numbers is 3 × 3.

## What is the HCF of 36 and 54?

18The greatest common factor of 54and36 is 18 .

## What is the highest common factor of 32 and 64?

Greatest common factor (GCF) of 32 and 64 is 32. We will now calculate the prime factors of 32 and 64, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 32 and 64.

## 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 36 and 84?

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