## What is the HCF of 32 and 54?

The factors of 54 are 54, 27, 18, 9, 6, 3, 2, 1.

The common factors of 32 and 54 are 2, 1, intersecting the two sets above.

In the intersection factors of 32 ∩ factors of 54 the greatest element is 2.

Therefore, the greatest common factor of 32 and 54 is 2..

## 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 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 36 84?

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

## What is the HCF of 98?

The biggest common factor number is the GCF number. So the greatest common factor 42 and 98 is 14.

## 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 are the factors of 54?
